IMac video glitches

About once a day I experience this strange graphical glitch.
http://www.flickr.com/photos/goochrules/3049656804 (can i get this image to display inline in my post?)
The color of the glitch vary, from yellow to magenta to cyan (light blue) to green. The pattern shown is typical, but the size and shape varies, and the pattern is sometimes mirrored, with either the upper left or right corner being the darkest.
The glitch goes away when the window it appears in is minimized, or the program is exited, or the window is obscured behind another window... basically anything that forces the area with the glitch to be redrawn. I am not sure if moving the window in which the glitch appears causes the glitch to go away.
The iMac is a 2.16GHz Intel Core 2 Duo, with 2 GB ram and a ATI Radeon X1600 graphics chip, running OS X 10.5.5.

Thanks for the reply!
I've tried to unplug everything (before was plugged only a4tech mouse and HP printer), and reboot the system. Nothing helps . i've performed reboot about 10 times. Also I've tried to reset SMC (unplug power cord for 15 sec, then plug 5 sec after, cmd opt p r) so sad. I can't use apple service in my country because of lack of service at all, only unofficial... Anyway thanks for replies... I will try to find the way to transport iMac to the nearest country with an apple service.... So sad, it was never happened with me, first critical issue with an apple device.

Video Glitch

I just downloaded the new software update for my mac. The software updates were: J2SE 5.0 Release 3 and the Mac OS X Update. I don't know if they have anything to do with my problem, but it never happened before them, just after I downloaded them.
I watched a DVD last night about a few hours after downloading the software update. The DVD would pause for less than a second, as if there were a scratch, but the DVD was in perfect condition. The audio was fine but it was a very quick pause. I thought that the DVD was scratched. This morning, I decided to make sure and put in a DVD. Sure enough, it does the same thing, so it has to be my iMac.
(I put in a different DVD this morning, just to make sure.)

What should I do? How do I fix this?
(P.S. This only happens in the DVD player, because I watched a trailer online, so obviously it's not any other video.)

Does the slight pause occur around the midpoint (say 1 hour 30) minute point of the DVD? If so, this is normal and common to all DVD players (both your mac, as well as all commercially available dvd players) as the dvd player switches over to play the second layer of a dual layer DVD disc.
Not all DVDs are dual layer discs, so that can explain why some dvds seem fine, while others arent.
The fine print on the back of the dvd box or in the insert usually tells you if the movie is on a dual layer disk, and that such a pause is `normal`.

Video Glitching- Lines and Patches on Screen

Hello.
This morning my three-year-old iMac G5 began exhibiting video glitches. The glitching occurs at all times, including the gray bootup screen. The display appears to be streaked all over with coloured lines which change colour and pattern when I move windows and objects around on the desktop.
http://www.gossi.co.uk/misc/screenjpg.jpg
An additional strange symptom is that this first occurred when I started up World of Warcraft. Now the above behavior occurs at all times with or without WoW running. 3D graphics in WoW are highly distorted, stretched and blocky.
I am aware of the iMac repair problem, although my serial number does not match up, and my iMac is second generation rather than first.
This seems very unusual, and doesn't seem to match many other graphical problems mentioned on the forums. Has there been any other issues similar to this reported?

To Apple Discussions!
"An additional strange symptom is that this first occurred when I started up World of Warcraft."
Are you playing this game off of a CD/DVD or is it installed onto your HD?
Which OS are you using?
*A couple of things to try prior to visiting your local AASP:*
Max out your RAM. Your system info confirms you only have 1GB.
Boot from your System Install DVD & run the repair disk/permissions option(s). If this works, then I suggest that every time you play WOW, afterwards repair permissions directly from the HD & restart your computer. However, you really should consider maxing out your RAM.

Help Needed : Video Glitch after exporting from Premiere Pro CC

Hi all ,
            I have been experiencing this issue for sometime now. I occasionally encounter a video glitch after exporting a video from Premiere Pro CS6 or CC. Sometimes it happens in my NLE timeline , which I have to remove the affected clip that has the glitch/flicker problem from my bin and re-import the clip from my original source, which solves the problem.
             However , the worst part is when the glitch/flicker happens when I have already exported the video when everything seems fine in the timeline of Premiere . My sequence settings do match with the clip . This issue happens intermittently as I always have to hope for the best when the video exports.
Here is an Example of what I mean, the glitch/flicker happens at 3:28 of the music video.
             Hopefully those who have the same issue can share how to troubleshoot this problem . Thank you.
Regards,
Elias Lo

what i did was install final cut pro. I dont have an answer for this but it finish my problem , how i came up with this idea well i have the new mac pro cilinder that looks like a trash can 64gb memory and all the toys to work fast but again the mov files cannot be seen in the desktop cause premiere and mac and windows and all this ******** they fight about , and i also have your problem big time o pn every export.
i have instal final cut onmy older slower imac and i can see everything and the export are perfect
so i just did that and its perfectly fine basicaly final cut does something that makes ur computer and adobe read all kinds of files frames format.   i try to explain this to this adobe premiere enginners but they just say uuuuhhhhh

Video Glitches with 10.5.2 & 10.5.1

I've had a number of video glitches with my 2x867 MDD with the OEM GeForce4 MX (32mb) card, an Apple 15" Studio Display on the ADC port and an LG 22" LCD on the DVI port when using 10.5.2. I have not noticed them booting off the Leopard Update DVD. What I see is flashes of mostly white boxes with green or black edges. The flashes are fewer with 10.5.2 than they were with 10.5.1, but they're not gone.
Also, from time-to-time, the LG monitor will be lost at boot-up. Nothing will display on it, System Profiler says there's only the ADC connected monitor, etc. even though the monitor shows that it's connected to the computer.
Anybody else seeing this?

Boys n Girls
I am Currently restoring my Power Book after a significant meltdown.
Thanks for posting I too saw the shearing effect but shrugged it off thinking oh well I'll just reboot!
If you are seeing this Buy a fire wire drive NOW and Back-up.
I suspect the Video update changed a low level feature in the power management routines and this resulted in my Power book cooking itself.
I've got a 12mth old Hitachi 7200 PATA drive in my Power Book after the Apple Drive cooked itself soem tim back and I have now got to back-up and restore my whole system. Luckiliy I have plenty of Big fast firewire drives around so I'm imaging the corrupt drive and going to run the Hitachi tool on it via a WINDOZE Thinkpad. Then a combination of clean install of 10.5.x and a migration assisted restore should do it.
I'm really not very happy though! My Time machine image did not restore and the disk repair did not work. I have a corrupted asl.DB ( the log file for Apple System Logs) and the mac won't boot from its internal drive.
I'll post the resolution here as it happens I'm at hour Disaster + 24 so I'm really cranky!
I suggest If you have a G4 Power Book you resist the temptation to install the video update.
Regards

"Doctor Who: The Classic Series" - Corruption and Audio/Video Glitches

Has anyone else had problems with the "Dr. Who: The Classic Series"?
First off, I am unable to download "Episode 1" of "Carnival of Monsters". I have tried to download on 2 different Macs and one PC, all stop around 90 MB (error 8008).
Secondly, all 4 episodes from "The Claws of Axos" are riddled with audio pops, coupled with simultaneous video glitches. During "Episode 2", it actually throws the audio out of sync for the remainder of the episode.
I highly suspect these files are corrupt at the server side. Just checking to see if anyone else has had similar issues.

Sorry, but there's no way to know. Apple doesn't pre-announce additions (except for limited pre-orders on albums) and there aren't any alerts for specific shows except for season passes which don't really apply to the Dr. Who Classic shows where every full story is a "season".
You'll just have to keep checking back from time to time.
Regards.

Iphone/ipad video glitches after upload thru iphoto/image capture...suggestions??

iphone/ipad video glitches after upload thru iphoto/image capture...suggestions??

If the problem only appears with iPhoto then it may be due to a bad pref file for iPhoto. It could also be caused by a bad cache or log file.
There are additional ImageCapture preference files located in the /Home/Library/Preferences/ByHost/ folder. Be sure to remove them also. Also remove the /Home/Library/Caches/com.apple.iPhoto/ folder.
There are two ImageCapture cache files located in the /Library/Caches/ folder. Drag them to the Trash but do not delete them as yet.
Now restart the computer and see what happens.

The New iMac Video

The new iMac video is either missing or damaged. Someone should tend to this.

Why would an audio track cause a video glitch?

I have a 1080 60p clip with no audio. If I create a sequence based on that clip, add a wav file to an audio track, then export using the H.264 60p custom preset with audio multiplexing to an .m2t everything looks fine.    However, if I export using the H.264 Blu-ray preset, 720p, 59.94, multiplexed, to an .m2t file the video has some stutters towards the end.   If I remove the audio track and do the same export, still muxed, the video is fine in 720p.   I get the same result if I start with a 720p sequence (i.e. addition of audio causes video glitch).
Edit: tried a different audio file, this time .mp3, same problem.
Edit: importing the muxed 60p export with audio, then exporting as noted in 720p has the same issue.
Comments?   Let me know if what I'm describing isn't clear.

Hi Jim - understood in an ideal world one would have source video footage, sequence, and output target all the same. Is it not common though for folks to have situations where there is more than one target output?
Anyway, I think I have a tree covering both roads if I understand your analogy. What is wrong with the following picture? I took the original 1080 60p clip, dragged it into a 720p 59.94 sequence, exported the video only. The exported video looks just fine in this case. I even tried different formats (Matrox MPEG I-Frame HD, H.264 Blu-ray muxed and not). It is all good.
Next I imported the aformentioned no issue video that is in 720 59.94 into a sequence that matches then exported to a matching format.   No issue with the resultant video.   Is this scenario not what you mentioned?   Start with video that matches the sequence and target output?
However, if I add an audio track, the video has some flashing/stuttering at the end particularly towards the top.   Why would exporting with or without an audio track in the above scenario make a difference?
In case it matters, the video came from a modified After Effects template. I don't own AE and paid another guy to modify the template. I will go back and ask him to render in 720p 59.94. Still, the above just doesn't seem right.

T510 Video glitching

I just received my T510 Thinkpad this week, and I was dismayed to find that whenever I move anything on the desktop (folders, application windows, etc.), I can clearly see video glitching that makes it look like every other line on the screen loses anti-aliasing and looks stairstepped. (Imagine every other line and shifted them 1 pixel to the right).
Just curious to hear if anyone else is having a similar issue, and if there's any driver update or settings fix I can do to resolve this without having to have it sent back for repair/replacement?
I'm planning on calling support, but thought I'd at the very least document this as a potentional model bug...
Solved!

Well, it seems that I was in energy conservation mode and the laptop shipped with the onboard graphics set as the default, so turning on the discrete video card and bumping up to optimal performance resolved the issue.
But thanks for your helpful responses!
So you are able to switch between the onboard and discrete video on your T510?

MASN2HD Audio & Video Glitching

I am experiencing audio and video glitching, with both dropping out every 15 seconds or so, while watching MASN2HD on channel 501. So far I've only noticed it while MASN2 is on 501 - I can't say whether Fios1 HD is also glitching. MASN2 SD on channel 1 does not have the same problem. I've experienced this on multiple TV sets. I tried powering off the DVR/STB with no change.
I was going to try resetting them through Verizon.com, but it gives me an authentication error whenever I try.

Cinemax HD Channel 920 - Video glitches?

Could you please forward this message to your Fios TV technical operations team?
I read a comment on another forum from someone with the same issue so I wanted to ask about it here:
I've been seeing a lot of mpeg video glitches onscreen on channel 920 lately, this is the only channel I am seeing this issue on. Seems to be between 10 and 40 times an hour (these are all relatively minor events lasting a couple of video frames for the most part).
I've noticed this for many months - sometimes the channel will be perfect for a few weeks or a month then it will have mpeg breakup issues for weeks. It seems to cycle between having video problems and not having video problems, so I don't believe this is any issue on my end as, like I said, this is the only channel I have any problem with.
On another forum someone commented it may somehow have something to do with the 'super head end' having an issue sending the video data to the local VHO (I am in VHO 15A), so I was hoping someone could check this out and maybe fix it permanently!
Thanks!

If anybody can tell me how to fix this I will be forever grateful! thank you!

I have the same issue and would love a fix. In my experimenting I came across a temporary workaround, and subsequently have a similar issue exporting from Motion 5. Still no real solution, but here's what I've seen:

IMac Freezing - No video glitch, but unresponsive

Good morning all,
In the past week or so, I've started to have problems with my iMac freezing. This has occurred while using iChat, playing World of Warcraft and while using Safari (not all at once).
In short, the video display seems to freeze. I can still hear audio (ie. the other person on iChat speaking), but everything else in non-responsive. The keyboard does not respond and I cannot ALT-Tab or open any other programs. My only recourse is to manually turn off the computer and try again.
It's usually a guaranteed failure when opening up Warcraft. About 4 seconds after the program has opened, the computer freezes.
I've searched the forums and have come across several threads that involve some sort of graphical glitch, from which I do not suffer. That being said, I thought a new thread might be appropriate.
Any advice would be greatly appreciated.
Thank you,

My iMac has been repeatedly freezing when I am working in Final Cut Express. It plays the sound but freezes the video. It has been a horrible experience to try to edit 'blind'!
I have vacuumed the air vents, installed smcFan Control (great to manual adjust fan speeds on all 3 internal fans), re-installed Snow Leopard & gone through copious hours as all the software updates each time I've re-installed, and I run the disc doctor program. It started happening around the time Steve Jobs said Apple would no longer use Flash. I thought it a Flash issue since it only has to do with the playback of video. Today I discovered that clips I downloaded yesterday were also freezing in my desktop Picasa. Meaning it's not Final Cut, or Picasa, and unlikely my video card as all videos streamed from the NET (on YouTube, etc) play fine, and in fact my videos that freeze on my iMac when uploaded to YouTube or Facebook play fine.
I am enormously and thoroughly frustrated, as you can imagine. I had 15 clips from the G20 Protest March yesterday and was not able to make an adequate video to upload out of them because the video keeps freezing, and losing synch with the audio - and every time you try to play it, it freezes in a different spot!!
Horrendous problem.
Today, then, following advice in this thread, I will try re-installing back an update or so on OSX - I'm using 10.6.4, and perhaps need to go backwards?
This is an awful problem and I am surprised Apple hasn't addressed it. Perhaps it only relates to computers a few years old?
A usually very happy iMac user who is very disgruntled these days...

Intel imac display glitch and involuntary restart

Just want to know if anyone else has experienced this specific problem, there are plenty of complaints about intel imac displays but I can't be bothered to sift through them all trying to find a match for my problem.
A couple of months ago I was watching a video in quicktime and noticed that my screen was glitching and flashing fragmented diagonal lines - like a commodore 64 loading type thing. Then the spinning-ball came up and a force quit didn't do anything so I had to force shut down. I started up and it occured again. Then the screen went blank/black, but still lit up, and restarted without me doing anything. It also got stuck during start up the second time this occured. I panicked and ran out to buy a 500GB external drive, backed up all of my work and then re-installed mac osx from disk, archive and install job. This seemed to sort it and for the following two months it seemed OK. No sign of any problems.
Since then I have updated from 10.4.7 to 10.4.10 (which I have suspicion that it screwed the firmware in my motu 828 firewire audio interface, costing me a £130 repair - but that's another painful story).
It happened again tonight (the screen thing, not the motu). And the ball came up and I couldn't do anything. Force shut down, restart - screen glitching again. Then I had 2 unexpected restarts, one getting stuck in startup. Then a successful startup but accompanied by the glitchy graphics, mainly red/pink pixellated diagonal lines flickering in and out. I ran a disk first aid - no problems. Did a disk permission repair. Shut down and ran a hardware test, the first few minutes of the test the screen was still at it but then stopped glitching, hardware test found no errors (it was an extended test too). Now I'm back on it and it's all OK.
Any suggestions/similar stories?
When it occured 2 months ago I had the original ram that came with the imac. Now I have 2x1GB sticks of crucial ram.

That's it! Well, that's what I have. Unfortunately, I don't know about the cause, but I don't ever recall having it prior to an update going back about a year ago. I recall an update, and that update being immediately followed by some sort of Apple Graphics something-or-other. I feel pretty certain that's when I first noticed this. I just had my LCD replaced for another reason, but I think you'll agree, it's not an LCD issue. In my case, browser activity, scrolling up or down in a page, seems to be the most common trigger. I've also seen "pieces" of the torn page, on the screen when minimizing the browser to the dock (usually Firefox, but I think I've seen it with Opera and Safari too). Is there a way to find update packages installed somewhere? I'd know it if I saw it, and I'd definitely try removing that suspect package/update.
