Created attachment 42979 [details] The screenshot doesn't actually match the screen, but it gives you the idea. The screen corruption "just happened" suddenly, and I was forced to SIGHUP the X server from a console to make it disappear again. The corruption was actually across the entire screen - the "normal-looking" region in the middle seems to be just an artifact of the screen-capture process. I am using xf86-video-ati from git, with Fedora 14 and a vanilla 2.6.36.3 kernel. The graphics card is a HD4890.
Created attachment 42980 [details] Xorg log file This is the log file from the X session that I was forced to SIGHUP.
I have just experienced this exact same problem with my RV350, on i686. This box also has a 2.6.36.3 kernel. This all started with the recent "page-flipping and tiling" commits.
Does disabling Option "ColorTiling" work around the problem?
I think the following bugs are probably related: bug 33929 bug 33952 bug 33943 bug 33963
(In reply to comment #3) > Does disabling Option "ColorTiling" work around the problem? It does appear to, yes, at least with the HD4890. BTW, this bug also affects my M66GL.
Does the xserver patch in bug 33929 help?
(In reply to comment #6) > Does the xserver patch in bug 33929 help? I had just enough "rpm-fu" to apply that patch to xorg-x11-server-1.9.3-4.fc14, and to date, I have not yet been able to recreate the screen corruption with the new xorg-x11-server-Xorg package. However, I never had a 100% reliable method of reproducing the problem in the first place... Initial impressions are favourable.
