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? (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. (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. |

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.
