Recently, gtkperf will tear my whole screen apart in awesomewm 3.4.9 when it gets to the drawing sections. I will try to take and attach a photo soon. I am using cairo 1.10.2 with xcb enabled. I just compiled mesa, ati-dri, libgl, xf86-ati from git today. This problem does *not* occur on a composited kwin desktop on the same machine. Using a Macbook Pro 2,2 with Radeon Mobility X1600. Using r300g.
Does disabling tiling help? Option "ColorTiling" "false" in the device section of your xorg.conf? If so this bug is probably a duplicate of bug 33929. You might try the xserver patch on that bug.
Yes, disabling tiling fixes it. I just tried this today and it is still occurring in new git builds. I guess it is probably a dupe of the linked bug. I haven't tested a git build of X yet, which apparently is the source of the bug.
Is this still an issue with a newer driver?
