[Bug 38198] Re: Garbled using open source Radeon driver

[Laurentiu Pancescu]

The corruption completely disappeared since I switched RenderAccel off
(I'm using Human exclusively for 3-4 weeks now, didn't happen once).
With RenderAccel on it's easily reproducible, by switching desktops or
minimizing/restoring windows. It looks like a driver issue to me. BTW,
EXA makes the corruption *much* worse on my system, compared with XAA.
