Display problem, and maybe worse

On startup this morning my iMac (PowerPC) G5 display began behaving very strangely. The screen is displaying my usual desktop picture, dock and icons, and finder window. Applications are running, but very oddly.
The screen is covered in small visible dots, some flashing, some static. When I open a document, or a page in Safari, it displays more or less normally (I can use Word, for example), by then "smears" if I start to scroll down the page. At other times the graphics break up completely.
I'm guessing this is a display problem, but one other odd symptom is that sometimes if I click on a file in the Finder window, instead of opening the document the window shuts down and re-opens in its starting configuration.
I tried a restart, but it stuck on a black screen, and I had to force it to stop via holding the start button, and start again from there. I tried accessing system profiler, and it all froze up, requiring another button stop / start.
It looks like a hardware issue, but I've no idea what kind. Anybody recognise what is happening? (I'm posting this from my iBook).

Since the update 10.9.4:
My soundcard is missing and on Safari 7.0.5 video artefacts and flickering.

  • Windows 7 64 bit on iMac display problems and instability

    I received my iMac 27" quad core with 8 gig ram & 2 x 1 TB hard drives last Friday. I'm using Boot Camp to run windows 7 64 bit on maximum 2560 x 1440 screen resolution.
    I get intermittent but often display problems in windows 7. I get areas of the screen covered in little yellow dots or blue squares (never red artefacts.) This will happen at random areas of the screen, inside an open window, around borders of windows and so on. Most often the screen will go black and come back with a message in the bottom right corner of the screen saying 'Display driver has stopped responding and has recovered' with the sub message saying 'display driver ATI radeon family stopped....etc'. Sometimes I lose the screen wallpaper. Once I've had the system just shut down, once I've had Photoshop seize up and I had to do a cold reboot. Could this be an overheating problem or resolution too high problem or driver problem? Windows 7 tells me my drivers are up to date. I tried installing the drivers for the card from ATI's website which made no difference
    The reason I bought a Mac is because it's the only effective way to code for the Mac family of OS's in XCode. The reason I didn't just attach a miniMac to my PC monitor was because there's rather a lot of advertising by Apple about the fact that you can use a Mac with a PC OS via Apple's own Boot Camp. Now I have a lot of Windows software (some of which is not available for the Mac or requires buying again) sitting on an unstable system. Any ideas would be much appreciated...

    Sorry, that thread got moved for edit and as a user tip... which I didn't want and won't be doing....
    Here is the post:
    A tip and workaround for how to get ATI mobility/laptop drivers so that Windows no longer thinks the ATI is a desktop card:
    http://discussions.apple.com/thread.jspa?messageID=11286987
    Summary (my own edit steps):
    1. Install Boot Camp 3.0 and upgrade to 3.1
    2. Uninstall graphic drivers and run Driver Sweeper
    http://www.guru3d.com/category/driversweeper/
    instead of:
    removing the crashing driver by going into windows 7 setup via its install cd and deleting the ati driver manaully
    3. Install ATI Mobility (link)
    4. Uninstall ATI (Programs control panel?) Device Manager (rollback; uninstall?)
    5. Device Nanager: update driver and BROWSE BACK to 8.681 (the original apple driver that was causing freezes and purple artifacts) - navigate to /Apple/Drivers/ATI
    (Apple uses) a 4850 card in the iMac, its modified a bit for apple. Enough that desktop drivers don't work, and modded-for-laptop desktop drivers don't work either.
    Now the upshot of using modified drivers is that it FORCES the catalyst control panel to be installed, meaning you get a few more options to mess around with the card.
    I couldn't use the original apple drive, it locks up, the newer one had banding, the newer radeon drivers direct form ATI wouldn't work until they were modded and then they cause black screens.
    SO the solution, as obscure as it was, was to download ACTUAL mobility Radeon drivers - version 10.3 still, but made for laptops.
    http://support.amd.com/us/gpudownload/Pages/index.aspx
    THESE drivers I was able to install - and here is where things changed.
    THIS driver changed they way windows saw the video card in device manager.
    As I mentioned before, its NOT a desktop card, its a modified laptop card, but installing mac drivers makes windows THINK its a full desktop card, and running the original 8.681 driver crashed it.
    Once installed 10.3 LAPTOP driver it now appeared in device manager as a MOBILITY card.
    +These Steps "should" work:+
    delete ATI driver manually
    reinstall apple driver after that and see if that works,
    otherwise try the steps above
    (mod drivers, remove via windows recovery off setup disk, install laptop drivers, reinstall apple driver over it)

  • IMac ghost display problems (and apple technicians weren't able to solve)

    Hi,
    So my problem here is quite weird. I tried researching the forum for something like this, but nothing really came close to whats happening to my iMac.
    I have an Intel-Based iMac, 24 inch screen.
    I bought it on 2008. Since late 2008/early 2009, i had these weird "letters" underneath all my pictures. I work with photography/video editing, so this was very annoying, yet i kept ignoring, since the rest was working fine.
    Then slowly the iMac ran slower, more sluggish-y. Like if all life was sucked out of it, sort of description.
    Then, 2 months ago, there was a total failure of the HD. I was lucky to be able to back up all, before it didnt let me even enter the computer. It would just think for hours.
    I brought it to the technical support near to my home, and i also told them about those weird "letters" on the left side of my screen. They said it was due to my hard disk, and i was, ok...since the hard disk had a failure.
    They did a check up, and yep, the hard disk was k.o, evidently. They replaced the hard disk, and told me all was fine.
    It did "seem" fine for the first couple days. No more running slow, no weird letters that would distort my pictures (for example, i could see my iTunes music list underneath a picture i was working on photoshop, or a video i was displaying!).
    After a couple of days...same story started again. The left side of the screen was flooded by all underneath (open windows, the desktop icons, the texts i had open on safari, basically anything would appear translucently underneath any image or video i would open). Then, flash player would crash every 3 videos, blank cd's would get automatically ejected so i couldnt burn any cd, computer would run slow etc... etc...
    So i cleaned up my computer, did a back up, erased all, and ready to bring it up to technical support again. And misteriously, all symptoms disappeared. So i explained to them what happened, and they said probably it was the graphic card.
    I thought finally my problem was solved.
    24 hrs later, i got an email that my computer was fixed. That it was only a hard disk "permits" issue, and they solved it.
    I have had the computer for 3 days, and the screen problem is starting again, and now the permits are perfectly fine in my computer, and nothing comes out as wrong in the diagnostics tool!!!!
    I didnt even work with the computer, but now i can see my itunes list through the safari window, as grey letters....kinda 3D, popping out. Its very weird. And i cant capture it because when i take a screen capture, it all appears fine.
    Left side of screen is the affected. And no, its not a condensation issue.
    Also, i can see some lines when i start up the computer. On the grey screen portion of the start up.
    I dont know what it can be anymore. I know this is a long post, but i had to explain all what happened to it.
    Any help would be great.
    Thanks

    You might want to clean up your profile. An iMac G5 will not run Mac OS X 10.6.4!
    My experience with things appearing on screen but not in a screen capture is that it is on the display itself and not involving the GPU.
    I think that you have image persistence, similar to CRT burn in. It is caused by having the same image appear in the same location over long periods of time, like a Safari window always in the same location, or an iTunes window, etc. The pixels get stuck showing that image.
    There are different little apps that folks have developed to get the pixels unstuck. Google LCD image persistence and you can find a number of them.
    Here is one suggestion;

  • T61 Display Problem and Annoying Noise from ESC button area

    I have two problems with my T61, model 6460-66U. One's with display and another is annoying noise coming from ESC button area.
    Ordered in Feb, 2008 for college use, as soon as I start to use it there's some problem with the display quality. When using Aero there would be black square spots appearing on screen and would disappear when hovering mouse over these areas. Processing speed is somewhat slow when using Aero. While switching to Basic Vista style, those black square spots will only appear in the Windows Photo Gallery's left corner, like the image shows: http://farm4.static.flickr.com/3149/2746362257_6dc6a4d6a2_o.jpg  When playing videos, like avi, rmvb, wmv files, there's a common problem that the screen in the media player keeps flashing with the green color. I thought it was the RAM, because it's 1G so it got upgraded to 3G over summer break. Hoping the problem would be solved, but not . Recover the system back to factory status helps a little, but after upgrading the newest driver (7.15.11.7597) of Nvidia 140m there would be sudden black out on screen, and notice of display driver stopped working. When degrade to 7.15.11.129 version it runs fairly well but problem with Photo Gallery and videos as mentioned above still exist. I found a Korean media player which could fix the video playing problem, but with Windows Media player, Realplayer and other major video player the problem still exists. Screenshot of the problem is here http://farm4.static.flickr.com/3087/2746362307_aff12c556c_o.jpg  I upgraded BIOS, but laptop would become slow and video images would blur/double shadows. So I swtiched it back.
    And recent few days, there's annoying noise coming from in the upper left corner, where ESC button is. I don't know whether it's from the fan or the AC adapter, it's like Zssssss, and if I press my finger on it, the noise would be a little louder. There's a similar problem that I noticed in the first few weeks with the experience of this laptop, whenever I maximize the volume (both volume control of computer and the music player), some annoying noise, which is similar to this Zsss sound but louder will buzzing along with music. Didn't care much about that since if I don't maximize the volume it would just be fine. But this time the whining noise won't disappear. What probably cause this?  Anyway to fix it, like replacing certain parts??
    Suggessions and help would be very much appreciated. Thanks!!

    Dirt can get under the button in an instant.
    I use a strong suction vacuum cleaner and tip the computer from side to side and upside down while clicking the button to suck out the dirt.

  • Display problems and the rest... Help

    When using the 'smaller' graphics card, the screen goes mostly black with horizontal strips of random colours. The only option is to perform a 'hard reset'. This happens 2-3 times a day (3 -4 hours usage).
    I haven't had any issues like this when using the 'hardcore' graphics card.
    That's the graphics issue... now the rest.
    EVERY time i start the thing up, the machine will reset itself within 10-20 seconds and then boot up fine.
    Sometimes it starts all the way... and then... restarts itself (happened once).
    What should i do? I bought from a reseller... and they are useless... Surely it's covered under warranty? No applecare... but then i should be protected under manu warranty.
    I've migrated from my older 17" macbook pro and that took 4 hours! i really dont want to go through that again.
    Will the applestore allow me to change the HDD?
    What do you suggest (anyone??)

    If you have a late 2008 MBP, then it is under at least a 1 year warranty, which you can upgrade to 3 year Applecare if you like. It doesn't matter where you bought it. You can call Apple or go to any Apple Store to have it looked at.
    I believe that in the late 2008 MBP, the hard drive can be replaced by the user. You will find instructions in the manual.
    But it sounds like your issues would not necessarily be fixed by a hard drive replacement. It would be wise to try to get a diagnosis first.
    A good place to start might be to run the extended version of the Apple Hardware Test, which is on Install Disk #1 of the original gray discs that came with your computer. If you get an error code of any kind, then you have a hardware problem that needs to be fixed.
    Do you have access to an Apple Store? If so, make an appointment with the genius bar and have it looked at.
    If you don't have a local Apple Store, call Apple on the phone and describe your problems to them. They can walk you through several troubleshooting procedures and hopefully determine what is causing the problem.
    Good luck!

  • Display problems and others

    I just bought this macbook in january and already when i'm scrolling on a web page the images flash at various parts of the page even if the page is fully loaded, this also happens in other programs such as powerpoint and word as i scroll...also it seems to be taking longer than it used to to start programs such as word when i have powerpoint and my email open at the same time...what can i do to get it to perform like it used to...i haven't added or downloaded any new programs really to take up any space on my hard drive? also my cd drive makes 3 loud, god-awful clicking noises anytime i insert a disc into it which has happened since the very first time i used it...is that normal or should i get it checked out?

    HI and Welcome to Apple Discussions...
    *"my cd drive makes 3 loud, god-awful clicking noises anytime i insert a disc into it which has happened since the very first time i used it...is that normal or should i get it checked out?"*
    That's not normal. I would definitely take the MacBook in for service.

  • Wierd lines on my display and frequent lock-ups w/ and w/o display problems

    When booting I sometimes get weird lines and blocks on my display (the GRAY Apple screen) and then it hangs, other times the computer will boot and run fine for 20-30 minutes and then the display goes wonkers with blocks and lines and the computer does not respond. The only way I can get it to boot is to reset the PRAM by letting it CHIME 3x and then occasionally it will boot without issue and run, while other times I still get the blocks and lines on the display.
    When I am able to get it to recover and re-boot after the lock-up and display problems and occasionally the box in the middle asking me to re-boot similar to a kernel panic the OPS gives me the option to REPORT the error and here is the error for others who would know more...
    Thank you in advance,
    Darren

    Anyone know what is causing my problems? I thought it was heat so I downloaded a CPU and FAN temperature monitor and the CPU was getting VERY HOT at first so I then ramped-up the CPU FAN SPEED to maximum - it turns out the CPU FAN was not rotating well at low speed - since then I have cleaned and checked the fans and they all work as they should and blow on high(er) when the CPU temperature is above a certain level.

    Is there a kb article or something that would illuminate what to look for in these logs, or is it a matter of learning by osmosis?
    Both. I am not skilled in reading logs. It is a very technical and time consuming task for the uninitiated (me!) In scanning a log I look for the backtrace and loading dependencies. The first item in the backtrace is usually the roadblock.
    Beyond that you can look at the Technical Note TN2063: Understanding and Debugging Kernel Panics

  • Conclusions so far on the display problems?

    After reading thread after thread about the display problems this is what I understand:
    Most of the 20-inch Alu-iMacs seem to have problems? Not being able to show solid colours without a gradient from top to bottom is the biggest issue?
    "Alot" of the 24-inch Alu-Imacs have problems with a left to right gradient, often white to yellowish white.
    Apple is not admitting that the Alu-iMacs have general display problems. (Maybe due to too cheap display technique?)
    We don't know for sure if it is hardware or software related?
    Is wait and see the best practice for one who want to buy a new 20-inch Alu-iMac?
    /Krister

    What I'd like to know is why? Could the bottom lamp be getting more power than the top one from the inverter board?
    I received a lot of these for our labs and most of them (I haven't opened them all yet) have lower lamps that appear almost twice as bright at the top lamps... It's in the hardware, and I don't know what to do about it.
    So, where is the problem? Traditionally the lamps (usually two below and two above) are identical models, so could this be an inverter issue? Has anyone tried to get a voltage reading from the lamps to see how much output the inverter is giving them? (Not at all suggesting, just asking. I know what Apple would say if I asked people to go cracking their iMacs open.)
    Could the layer of glass in the LCD be refracting more light toward us in the bottom 2-3 inches and away from us for the top 2-3 inches?
    It's frustrating to experience, but worse to not even know what causes it. Because, to Apple engineering... What problem? There must be one bad LCD out there... and we all have it.
    Anyway, anyone who has any light to shed on the subject I'd love to hear it... (just add it to the top few inches of my display.)

  • MBP 13 retina late 2012 - display problems with wifi

    Hello!
    I writing you about a problem i'm having since i bought my MBP retina in October 2012 but now that i'm in Russia is really worring me. I've been in a Genius Bar back at home in Italy but i couldn't show them the problem with the display because it was very occasionally and it never happened while i was in the apple shop. The apple genius run a kind of testing program and apparently my mac is ok. Now i also know that this problem happens only when the wifi is on. The display is flicking ( i hope this is the correct word) and actually it was just rarely in italy but since i'm in russia i can't use my mac while i'm connected because this problem is constant and much much stroger.
    I noticed that the only way to stop this problem is to make a bridge with my finger from the alluminium chassis of the mbp to the black part at the bottom of the display. If i do this the flickering stops. So i'm somehow thinking it is an electric problem, and maybe in russia there is a different tension in the electricity or something else that makes this problem bigger.
    I will also traveling for the next 5 months and so i can't bring my laptop to an apple store in italy. I don't know if i can bring it to another apple store around the world to fix the problem, and i don't know if i will have a 2 years warranty like i have in italy.
    I'm very angry with the genius i've been in italy because he didn't believe my problem and he didn't investigate further. I was there in April or May and i still had the first year warranty. Now i'm traveling for the next 5 months and i super need my mac because i'm a travel blogger and as u can understand it is very important for me.
    I hope someone can help me.
    Thank you
    Dan

    thanks! yeah i recorded it so i hope they will take the problem more seriously.
    Unfortunately i don't have an applecare protection plan, but i hope that the proof that i've been in an apple store for the same issue already in april will help me somehow.
    I also think that when i touch with my hand both chassis and display i make some connection working again. Maybe i'm the radioactive man, or i have some special powers...or for the first time time in my life i bought a bugged apple product. But i think is more possible one of the first two options!

  • Ideacentre B320 display problem

    I'm suffering from a display problem, and cannot figure if it's a software or hardware issue... I'm on Win7 64bit. Here are the symptoms:
    1) For a while now, intermittently the screen would go grey (or some sort of a messed up pattern of rgb pixels) and I would have to power down forcefully. The frequency of this has gone up very much in the recent weeks
    2) When the machine freezes, I can still hear the music playing, and Windows continues to do whatever it was doing before
    3) Recently (I'm guessing after a Windows update), I wasn't able to boot into normal mode anymore. It would show the Windows splash screen, then before the login screen appears it would just go black and freeze. Leaving it for a long time doesn't lead to recovery
    4) To try and fix this, I've updated the ATI driver to the latest version, which didn't work so progressively tried every version between the11.6 and 10.3 (4?) which was the default when the machine was purchased. No luck there. I've also flashed the bios and that didn't help either
    5) I can boot into safe mode, so I disabled amdkmdap using sysinternal's autoruns.exe, which meant that I can boot into normal mode, but it woud fall back onto Windows' vga driver (1400x1050 only!)
    6) Now, even in the low res mode, almost daily the grey screen freezing would happen and I would have to reboot. Tapping the power button allows the shutdown dialog to come up (I'm guessing), and pressing enter would shut down the machine then.
    There's an awful lot of posts on the internet regarding people having issues with ATI HD6450 and similar category cards, some of which sound similar to my case. They too experienced the freezing problem and reverting or upgrading the drivers had no effect (many even reinstalled windows completely). It sounds like though, the problem is software in origin at a guess.
    On the other hand, the machine is now 3-4 years old and I could imagine that the GPU or graphics memory might have suffered wear and tear -- emailing Lenovo support took a week to get a response, the only thing they asked was whether my warranty is still active (after that it's been a complete silence) are they usually this terrible?
    The last thing is, when the problem first occurred I booted using a linux live CD and it was all fine, at full resolution graphics. I haven't repeated this experiment since it takes quite a while to boot from a CD... but suggested that the hardware is intact. In fact, by messing about with the drivers I was able to boot into Windows normal mode and operate for 1-2 days, after which the grey freeze happened again. I haven't been able to get back into that since.
    Here is my question: Is there a way to find out whether it's software or hardware that's at fault? If it turns out to be hardware, what are my options at replacements? The GPU is soldered onto the motherboard, so do I have to replace the whole thing? If it's a software issue, would restoring to factory default state fix this issue, given that an unknown update could cause the same issue at any time... This is the last time I will buy an AIO without removable everything. 

    Welcome to the Lenovo Community !
    Probably a good test of the hardware is use the Linux Live CD that you used earlier.   If the graphics are still good when using the Live CD then your monitor and GPU are fine. 
    If the hardware checks out Ok then I suspect you have a driver problem.  Try using a driver cleaner to fully uninstall the ATI driver since bit and pieces left over from previous driver installs can cause problems.  The link below is for a free and highly recommended utility for cleaning the system of the graphic drivers.  After the clean up I would try installing the original driver that came with your system.

  • Display problem after apple repair

    Hello everyone,
    Few weeks ago had this problem with vertical lines on my iMac display, which apple told me it was a display problem and they needed to changed it. So far so good... despite the 300pounds i had to pay for a new screen but anyway....... now look what happened...
    i was wondering if anyone has seen this problem before (i wish i could browse on internet about this problem, the thing is: with my screen like this i cant distinguish what is or isn't a good image when i watch videos/pic posted from other users regarding displays problems)... do you think is any graphic problem? or display again?
    i'm so upset
    Thanks

    Thanks for your reply.
    I've just done it and the screenshot looks fine on my iphone. So... LCD problem again...? great
    can you see any problem on this screenshot?
    Thank you for you help.

  • Help needed identifying display problem

    I have a 17 inch Powerbook G4. I saw that a lot of people have got display problems and unfortunately I have too. Hopefully you can help me figure out what’s exactly wrong so I can try to fix it!
    Here are the symptoms:
    The upper third of the display is working fine.
    The middle and lower third of the display are darker / faded and flicker a bit at around 20/30 hertz. (But this part is backlit, only a lot less)
    No other symptoms, also the grey part isn’t deformed)
    What I would like to know is, if someone can tell me if this is the Logicboard / Inverterboard or the Display itself.
    Thanks in advance for your help!!

    I have run several tests. Nothing seems to be wrong with video memory or so. The external display port produces a fine image on an external monitor too.
    I have made some pictures of what the screen looks like:
    http://www.renessance.nl/powerbook/display01.jpg

    http://www.renessance.nl/powerbook/display04.jpg
    http://www.renessance.nl/powerbook/display05.jpg
    The bad part is harder to read, doesn't get really black and flickers @ 60hz or so.
    So I'm still wondering if it's the inverterboard or display itself.
    Your help is really appreciated!

  • Duo Displays Problem on MacBook Pro (13-inch, Mid 2012) Resolution 2560x1440 and 1280x800, Sometime 2560x1440 is blank screen and must restart to fixed it

    Dear all,
    I found some problems for using Duo Displays with MacBook Pro (13-inch, Mid 2012) display and Samsung UHD Display (U28D590). I use resolution on my macbook is 1280x800, Samsung UHD Display is 2560x1440 And Connect with Display port to mini display port.
    But I use sometime found always blank screen on Samsung Display and I tried to unplug mini display port and plug it again but it is not working until I shutdown and restart my macbook pro, my display back to working.
    I want to fix this problem because it is very trouble for my working a lot.
    Thank you very much
    Phot

    The symptoms I'm getting now, and I'm not sure if they're any different, suggest that for some reason Mountain Lion thinks my display resolution is higher than what it is, as wether I'm turning AirPlay on or off, it keeps changing it (on the MacBook) to what looks like maybe 1080p.

  • Timeline - Cannot Move Tracks and Display Problem

    I've created about a ten-minute timeline that I'd really prefer not to toss out because a lot of work went into creating parts of it and getting the timing right with the music, etc. When I first open the project in Premiere Elements, everything seems okay - my timeline plays with all transitions and I can scroll around in the timeline. However, I appear to have done something where whenever I click and drag to try to move a track, the timeline goes insane. I get a circle with a line through it for a cursor and a blank tooltip window, whether I try to drag the track horizontally or vertically. After that, while the timeline will still play, the timeline itself gets all wonky in its display, almost as if the video isn't refreshing on it. (It's kind of like the timeline has crashed.) I attached a screenshot of what it looks like. Whenever I move my cursor to the edge of the timeline, the timeline scrolls in that direction.
    I'm running Premiere Elements 7 Educational Version on  a Core 2 Duo laptop with 3GB RAM, an Intel 965 graphics chip (latest Intel drivers are installed), and Vista Business 32-bit. The clips are from a standard DV cam (not HD), and there are some PNG format stills and MP3 sounds mixed in there as well. There are three active A/V tracks. I think that's all the relevant information, but ask me if you need more.
    Can anyone tell me what I've done and/or how to fix this?

    Good morning every one!
    The bad news: As expected the problem does still occur. The good news: I was able to track it down to one clip in the timeline.
    To save others time, I will described what I have evaluated quite detailed in the following paragraphs...
    As it seemed to me that deactivating the Windows indexing service made the usage of PrE more stable I thought that maybe file locks would cause the trouble. So I verified this by opening the project in PrE, writing and executing a small Java application that puts an exclusive file lock on one of the files from the project and tried to move the according clip in the timeline. It worked without any problems and the known symptoms did not occur. So we can put aside the file locks.
    Afterwards I tried to reproduce the problem by playing around with the scene that caused problems last week. I tried by moving around the video clips and the problem did not occur. Then I remembered my statement I have made earlier, that the problems seemed to occur as I started to work with titles and music clips -- and bingo: I have three music clips in my "soundtrack" track and one of them seems to cause the whole trouble. After I have clicked on this specific music clip, the problem occurs and it is no longer possible to move anything in the timeline and the strange behaviour regarding the automatic scrolling when the cursor is at the left/right etch is activated.
    It was easily reproducable: Restart PrE, open my project, move a video clip to verify that moving clips works, click on the specific music clip and the problem occurs. I have tried this several times and each time the problem occured. When I clicked on one of my other two music clips everything was fine -- same for the video clips I tried. So in my case it seems to be this single clip.
    OK, what's specific regarding this clip: All my music files are placed on a share on my Windows home server (in contrast to the video footage which is located on the local HD). So I moved the "dangerous" music file to the local HD, changed the path to the file with a text editor directly in the PrE project file (which is a simple XML file) and started up PrE again. I verified that PrE takes the file from the local HD (server was down), but the problem did still occur. So it is not a network issue.
    The next specific thing is, that this music file is the only file in my project which is a .wma-file -- the others are .mp3-files. So I did three things:
    At first I downloaded the project file provided by SQFreak2 in this thread and checked whether he is also using .wma-files. The result: He does not use them.
    As the second thing I again changed my project file in the text editor: I changed the path of the music clip to some other .mp3-file. Afterwards I opened up PrE with that project file, used the playback to verify that the other music file is referenced by the clip instead of the original wma-file and then tried to move the clip -- again the symptoms occured.
    As the last step I created a new project, added the "problematic" wma-file, placed it on the "soundtrack" track and afterwards tried to move it. The result: No problems at all.
    So it neither seems to be a generic problem with wma-files nor does it seem to be a file-specific problem at all.
    Lets summarize the things from above: File locks do not cause any trouble. In my project a single audio clip seems to cause the problem. The problem seems to be caused by the clip and not the file referenced by the clip (no matter whether local or server based, wma or mp3, the problem occurs in every case).
    What I have learned? Well, I am not sure. But in the meanwhile I am quite sure, that it hasn't to do anything with hardware and drivers, but that we are dealing with a bug in PrE that occurs in specific project cirumstances.
    This morning I have got some additional ideas I would like to try to track the problem down (e.g. the problematic clip has a transition for a fade out in the end [when I did this I didn't knew, that a fade out could be easily achieved in the clip's properties] -- I will try to remove this one and look what will happen).
    P.S.: In one of my earlier posts I stated the assumption that the problem occurs as soon as I move the mouse cursor over the vertical scroll bar of the timeline -- but this is definitely not the case.

  • MacBook Pro and Cintiq 12UX display problems?

    Hi,


    I'm not sure if this is the right place to post this so I'm sorry if it isn't - this is just the only place I could think of to ask about a display problem?
    I’ve just got the new model Cintiq 21UX, and I’m running it off one of the newer model MacBook Pro’s (using Apples adapter to connect the two).
    Everything seems to be working fine, although on the Cintiq’s screen I get flickering green pixels in darker areas of the screen? The confusing thing is it doesn’t happen all the time, it just seems to be the one particular ‘shade’ of dark grey/dark tones it happens on - an example is if I move an image around then its the same area of colour it has problems with across the screen, or if I zoom in the effected area gets bigger etc. I can also edit the colour to a slightly different shade and the problem stops so it can’t be a dead/frozen pixel. If I turn on the mirror display option it is still only the Cintiq display that is effected.
    I currently run the MacBook using the Nvidia 9600M GT, I did try switching to the 9400M but it made the situation a lot worse and caused green pixels lines to flash horizontally across the screen.
    I can save the image or drag the window that the problems happening on and drag it back to the MacBooks’ screen and there is no problem with the pixels there - it’s only on the Cintiq display.
    I was just wondering if this is either a fault with the Cintiq tablet itself, or possibly a problem with the MacBook?
    If it’s useful the spec of the MacBook is:

    Late 2008 unibody 15.4”
    Mac OS X v10.6.3 Snow Leopard
    2.8 GHz Intel Core 2 Duo
    4 GB 1067 MHz DDR3
    Nvidia GeForce 9600M GT & 9400M
    I’m not sure what other spec would be of use but if theres more I can let you know.
    Any help would be appreciated, as it works fine other than this occational green flicker, and it’ll cost me a lot to send of either the Cintiq or the MacBook off for a service or replacement in the UK?
    Cheers!

    It could just be bad. Do you have another computer to try it with?
