Description Matthew Monaco 2011-02-10 20:11:54 UTC 
I'm running Arch. This happens with r300g but not with r600. I'm not exactly sure what triggers the mess, but running winecfg does it every time. The screen becomes unusable, but I am able to switch to a virtual terminal and restart X.

The best I can describe what I see is diagonal misplaced tiling, like repeating stairs from top left to bottom right across my screen.

I git-bisected to the very last commit before 6.14.0:

mesa 7.10.0 (git built on Feb 6, 2011)
xorg-server 1.9.4

The specific card is: 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]

There's nothing in the Xorg.#.log file at the default verbosity when this happens.

Oops, forgot to mention that the issue still occurs as of the latest commit (	39104c6e8461cf49c1bb03a18858ad75a9d98b46 -- remove EVERGREENSetAccelState())
