Your bugzilla wouldn't permit the video attachment, so here's some links: http://launchpadlibrarian.net/29420273/23072009011.mp4 http://launchpadlibrarian.net/29420275/CurrentDmesg.txt http://launchpadlibrarian.net/29420289/glxinfo.txt http://launchpadlibrarian.net/29420306/23072009011.ogv http://launchpadlibrarian.net/29420355/lesson02.py *** Bug 22987 has been marked as a duplicate of this bug. *** Looks like fifo issues to me. You might want to try with current drm-intel-next, which has some fifo fixes. Yep, looks like FIFO underruns to me too... Fixes are in Eric's tree queued for 2.6.31.

Created attachment 27963 [details] XorgLog.txt I've seen this with compiz on and off. With compiz _on_ I get wild screen corruption when doing anything like flipping workspaces. With compiz _off_ the same effect happens when running a simple python opengl program. Will attach a video taken with my phone mp4 format, hope you can play it because the ogv version made using ffmpeg2theora is vastly accelerated frame rate, but does show the issue. Also will attach the python code which causes the issue.
