Created attachment 500584 [details] Screenshot of a corrupted window Description of problem: After using the system for a while X will start apparently rendering small chunks of the screen in the wrong place, on top of what should be there. Sometimes these misplaced chunks seem to get permanently stuck but more commonly they will vanish the next time that piece of screen is redrawn. How long it takes before it starts happening seems to vary from a few minutes to a day or so but once it starts only restarting X will fix it. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.10.1-14.fc15.x86_64 xorg-x11-drv-nouveau-0.0.16-24.20110324git8378443.fc15.x86_64 kernel-2.6.38.6-27.fc15.x86_64 How reproducible: Only thing that varies is how long it takes before it starts to happen. Steps to Reproduce: 1. Start X 2. Use it for a while 3. Wait for it to start going wrong Actual results: Screen corruption (see attached example). Expected results: No corruption. Additional info: Smolt profile is http://www.smolts.org/client/show/pub_1d8a121e-d189-4da8-b7dc-2cde99d94c75 and I will add attachments with various log files etc.

Having now experienced this a few more times it seems that it actually affects individual windows, and restarting the application whose window is affected seems to fix it.
The problem still persists. After a while it becomes so annoying that makes work almost impossible. Image of corrupted screen, Xorg.0.log and list of installed mesa* and xorg* packages attached.

(In reply to comment #4) > Having now experienced this a few more times it seems that it actually affects > individual windows, and restarting the application whose window is affected > seems to fix it. Do the same windows produce the same glitch every time? Please explain that a little, if it's the same application whose window is corrupted, or it is independent of an application running behind it.

That machine was upgraded to F16 some time ago and I don't think the problem is occurring since the upgrade.
Great. Thanks for the info. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
