Crazy corruption on screen

Hello.
I'm experimenting a weird kind of corruption mostly on images but also anywere else, for example on gnome-terminal.
This is an example of the corruption I see some times on images while browsing the web.

If I reload the page, the image usually reloads OK.
I have seen the same kind of corruption while working on gnome-terminal, in which this red matrix-looking pattern was also mixed with the desktop wallpaper I am using.(I am using a slight transparence in the terminal, if that helps)
It just started to happen yesterday, and the only update I can think of related to this is freetype2-infinality, which I uninstalled, and tried using the patched fonts from Ubuntu, and then got back to infinally, and in the meantime I had to reinstall and replace some stuff, kind of a messy update... :S
Has anyone experienced something similar to this or has any idea what it might be?
Thanks!

I am using the intel drivers in extra, updated today to see if that was the cause, but after the update I still have this issue.
I am now using extra/xf86-video-intel-uxa
And my card is this:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
I must say that I used a script to install the system, called AUI, and I remember choosing Intel GPU when asked, but I see that in the repository there is also extra/xf86-video-intel-sna.
Thanks!

  • IPhone showing crazy colors on screen when recording video?

    I seem to be having a problem with my iPhone when I go to record video. I get this crazy colored looking screen (it shows up in the video and you can see it on screen when recording). Any ideas as to how to fix this?
    Thanks in advance,
    David

    Hi David 14,
    Thanks for using the Apple Support Communities. I understand that you are experiencing issues recording video on your iPhone. If you haven’t already done so, I would recommend forcing the camera application to close and restarting your device:
    Get help with the camera on your iPhone, iPad, or iPod touch - Apple Support
    https://support.apple.com/en-us/HT203040
    2. Force the app to close, then open the Camera app again.
    3. Restart your device, then open the Camera app again.

  • New MacBook Pro, fan goes crazy on iPhoto screen saver

    I just got a new 15in MacBook Pro (running Lion of course) with the following specs:
       - 8 gigs RAM
       - 2.2 GHz
       - 500 gig 7200 hard drive
    I had my screen saver set to cycle randomly through 350 pictures from my wedding. Within 1 minute of the screensaver activating, my fan kicks in full speed. When I go into Activity Monitor (while the fan is still going nuts) no processes are using more than 7% CPU. Within a couple of minutes of resuming work, the screen saver dies down and everything is fine.
    Does anyone know why this is happening? I'm a programmer and even having multiple applications in active use, the fan doesn't kick on. If I switch to Arabesque screen saver, the fan doesn't act crazy. I suppose it's not a big deal to use a different screen saver but there's no logical reason for my fan to go insane when all it's doing is cycling through some pictures.
    I did try the steps to reset the SMC but it did not seem to solve the issue.
    Any help appreciated!

    You were right One of my other iPhoto albums must have corrupted pictures because I went to a backup that contained only the wedding pictures and everything is fine. Always nice when the answer happens to be something simple!
    Thanks!!

  • Using Cinema Display with mid-2010 MBP, post-Yosemite:  corrupted MBP screen

    For a couple years I've been using a 27" Cinema Display attached to my mid-2010 MacBook Pro 15".  The dual-display setup works great for my home setup.
    However, since upgrading to Yosemite, the MBP display often completely corrupts and reverts to complete gibberish, with fragments of the UI and desktop littered all about the screen.  Dragging a window over to that screen usually "redraws" it sufficiently enough to keep working, but soon the problem re-appears.  The screen of the CInema Display (my main working area) never corrupts, only the MBP screen.
    My setup worked great in Mavericks, but something in Yosemite isn't driving both displays properly.  Can anything be done, aside from downgrading to Mavericks?
    Andy

    I am having this exact same problem.  2010 iMac with NVIDIA GeForce 9400 256MB.  I have it hooked to a 30" display through a DisplayPort to DVI-D adapter.  The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
    This all started as soon as I updated to Yosemite a couple days ago.

  • Crazy Yosemite Login Screen.

    After I upgraded to Yosemite on my MBP (early 2011), at least once every few days I will open my computer to a login screen that looks like this.
    The screen is never frozen, and I can type in my password and log in, but it just looks crazy.
    Also, sometimes if I open my computer within a few minutes of having previously closed it, it will load all my previous windows, freeze for a minute, show the login screen like it wants me to enter my password, and then it reverts back to allowing me continue my work.
    These are two oddities that I noticed after installing Yosemite, and I just didn't know if anyone else had anything similar happen to them.
    Also, before I upgraded OS X, my computer has been running pretty slow and I've observed a couple other weird glitches that I did not document.
    Is it possible that my HDD is on the brink of failure?
    Any input would be appreciated!

    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
    Keeping your confidential data secure during hardware repair
    Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

  • Images all corrupted on screen in CS4

    I just installed CS4 and when I open any image it either has a weird screen over it or a bunch of triangles, some black and some from the image.  Doesn't matter what type of image.
    I tried removing cs4, turning off virus protection and reinstalling but same problem.  CS3 and Lightroom 2 work fine.  Images look OK in Bridge.  Running Windows Vista 32 bit, 3MB RAM, Intell Core Duo 2 CPU, ATI Radeon Graphics HD 2600 XT Processor and I did look for the latest driver update in the graphics processor.
    Doesn't matter at what size I view the image--it just changes the type of corruption I see.

    Update to Photoshop 11.0.1.
    Make sure you have the lastest video card driver (from AMD in your case).
    If those steps doesn't solve it, you need to contact AMD - something is wrong with your GPU or driver software.

    I solved this myself by removing all desktop files from the user account that was causing this, and placing them in to the documents folder instead. I think the computer couldn't keep-up with imaging the screen and while dealing with it's folder operations every time I logged into or out of this user. By clearing the desktop, I have had no more problems.

  • Corruption on screen recordings - Captivate 6

    I am trying to capture some simple data entry screens in Captivate 6.
    However I keep getting artefacts in the output SWF file .. horizontal lines and the remnants of previous screens text boxes.
    Have experimented with loads of different settings ... othing helps..
    Does anyone have any ideas - before I ditch this thing and use Camtasia !!

    Thanks for the reply Rod
    Unfortunately, no matter what I try with relation to the settings it makes no difference.

  • No, I am not going crazy. My screen cracked shattered on it's own overnight. Broken glass

    Excuse the title, I wanted to put as many keywords in as possible so as many people can find this post.
    I've only seen 2 posts from people so far regarding this.
    I left my phone on my bedside cabinet last night, it was not on charge.
    I woke up this morning, and picked up my phone. Started to send a text, and noticed the screen wasn't functioning properly.
    Curtains were closed, so light wasn't great in the room.
    Came downstairs and noticed.
    The phone has been used for 4 days.
    I have NOT dropped it or damaged it in any way. That is clearly obvious by looking at the handset and it's condition.
    Sony now say I have to send it away, and potentially if they deem it to be my fault (which it isn't) I will have to pay £15 for it's return. This is atrocious considering the issues they had with the Z1/2 with glass cracking (which I wasn't affected by, nor even aware of before this morning)

    Sorry to hear this but the only advice we can give as a user led support forum is to either return this to the place of purchase or contact Xperia care which you have done if I'm reading your post correctly

  • Crazy Ipod touch screen, HELP!

    When I plug my 4 gen ipod touchh into my computer itunes recognizes it but when I turn it on all I get is a blank white screen. What do I need to do?

    Try to let the battery run down and connect in recovery mode to restore after that.

    I have uninstalled it and re-installed it 5 times. I have Windows XP and the latest version of Reader. Please help me!!

    Hi badkitty23,
    What version of Adobe Reader are you using and do you see the same behavior when you open Adobe Reader without opening a PDF in it?
    Also try to open any other PDF, you can try this one: http://helpx.adobe.com/content/dam/help/attachments/Acrobat_Reader_ReleaseNote_10.1.3.pdf

  • Crazy plaid-Like screen at start up

    Momentary before OS X window appears. Have worked with Apple Support on phone but no help. Tried Test users. Used Tech Tool & etc.
    Is this a problem?

    You need to document a complaint to Apple. I don't know how that could be done, but they already have a complaint on your Applecare claim number. I would say call them up again and hope to get a more helpful technician. Maybe someone else here has a better idea.
    Just one question. After this checkerboard pattern does all work OK after that?

  • Boot failure - white screen corrupted with yellow repeated bit-pattern.

    Hi
    I have had a quick look at the postings esp those with pictures and can't find a similar prob to mine. My white 24" iMac hasn't been able to boot for months now, except a couple of times but it then subsequently started playing up. As well as a boot failure the white boot screen has yellow bit-patterns on it, usually horizontal or speckled. I have been able to run the diagnostics program from the OSX disc but it didn't find any problems. The computer displays and animates the spinning wheel while booting, but overlaid on the corrupted white screen, and then 99% of time gets no further.
    I have made 5 screenshots with my 3G iPhone, the first two are of one boot attempt, the third is another boot attempt (note slightly different bit pattern - this one is the most common I get) and last two are of a successful boot attempt into AHT (Apple Hardware Test). If anyone recognizes this type of screen problem please do reply.
    Standard boot attempt (1) - two photos showing spinning wheel:

    Standard boot attempt (2) - one photo showing typical screen corruption:

    Hi, I am having a similar problem from what you described, but I can't even get the disk up and running for a clean install with Snow Leopard.  I'm curious if you have found a solution.  I fairly certain that it is not an issue with the hard drive. 

  • T500 Windows 7 Screen Corruption

    I have reasonably new T500 (2242-CTO) that was originally loaded with Vista and 'downgraded' to XP. I've been forced to rebuild the machine and decided to go straight for Windows 7.
    The T500 is noted as supporting Windows 7 and has been built as per the Lenovo instructions, here...
    http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-74108
    The build is done from a clean hard drive. I have run the build twice, once using ThinkVantage System Update 4.0 and a second time installing Windows 7 drivers in the specified order. Both resulting in the same problem.
    Windows 7 (Ultimate, x86 version) fires up fine and runs with the Aero interface and everything looks fine. Transparency and window animation etc. is working. But after using the machine for a short time and opening up an application or two I get blocks of screen corruption, typically in areas of the screen being repainted. The corruption can be seen anywhere on the screen, including the taskbar area. Minimising then restoring typically cleans up the screen for a while.
    On one occasion I heard what I believe was the hard disk powering down (a faint clunk) and corruption appeared at exactly the same time. 
    The machine has the Intel X4500-HD graphics accelerator and if the driver for this is not installed then no corruption is seen (but the Aero interface isn't supported.)
    When I used the Lenovo System Update method to build the machine there was a PC Doctor utility. The PC Doctor UI became corrupted prior to running diags but all of its video diags ran, looked fine, and passed.
    From a graphics point of view the machine worked flawlessly under XP.

    I had a very very similar problem with my x200 running on an Intel integrated graphics GPU (x4500).  The work-around I found to eliminate this visual tearing problem was to disable Intel "VT-D" in the BIOS.  I have absolutely no good reason why this works, but it did the trick for me.
