With kernel 3.0 the system boots up OK, and 3d accelerated composite desktop works as expected (with compiz 0.8.4), but if I run a game (I only tried this with ut2004 at fullscreen), and exit it, the compositor goes crazy: windows appear at random positions, on wrong virtual deskops, parts of windows appear instead of other windows, some windows become black, and these go on at random. On top of this, every animation flickers, and basically everything becomes a mess. With 2.6.37.6 everything is fine.
Can you bisect?
Well, I know how to bisect, but this one seems like a week-long job to me. I'll see what I can do about it.
The symptoms sound somewhat familiar. Can you try the patches from this thread: http://lists.x.org/archives/xorg-devel/2011-May/021908.html
(In reply to comment #3) > The symptoms sound somewhat familiar. Can you try the patches from this thread: > http://lists.x.org/archives/xorg-devel/2011-May/021908.html I git cloned the xf86-video-ati repository, applied both patches from that ml-thread, replaced the radeon and ati driver modules of xorg with the compiled ones, and now everything seems to work correctly.
I've gone ahead and pushed the patches: 9493563c1ef4b51af0ee8a44cb4e7c5bb280347e d29bab632e9ecccba518d4107d52620bf75eb1cf 104b2d7c071f29266b1bc4184a74e9714d14febc
