This is what happens on my toshiba a215-s7416 : Everything is just fine while using XAA, however using any compositing manager or EXA ends up with coruptions on the screen. The coruption is most intensive in compositing in use , a bit smaller in EXA. Also it seems that changing CPY mode to performance instead of dynamic almost makes those issues goes away ... Corruption with the Turion CPU always set to 1700Mhz is quite hard to notice and a lot smaller then when using on demand mode. This happens while running kubuntu jaunty with 1.6 rc2 xserver, xorg 7.4 radeon driver 1.6.11, mesa 7.3 kernel 2.6.28. The same thing was reproduced in KDE4 with kwin and in GNOME with Compiz. Previous release of ubuntu had the same problem, and this also happens in Archlinux. Here is a video example (10MB) of the problem while using kwin cube effect : http://www.mediafire.com/?yfo1gddztbw

Does disabling DFS help? Option "AccelDFS" "FALSE"
(In reply to comment #4) > Does disabling DFS help? > > Option "AccelDFS" "FALSE" > Nope it does not ... I played with some things (after reading man radeon) that seemed to be a possible solution for the problem like : Option "DisplayPriority" Option "RenderAccel" Option "AccelDFS" Option "DefaultConnectorTable" Option "EXAVSync" None of those helped.
Hello, I have also exactly this bug. I have this graphics card : 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] and I use debian experimental packages for the radeon driver : version 6.12.2. I have also the bug 16452 (small textures are not good aligned), maybe it is related?
Created attachment 25261 [details] [review] possible fix Does this patch (against xf86-video-ati git master) help?
I've seen massive corruptions only with radeonhd (also rs690). So I applied the patch to the radeonhd driver and the corruptions went away. Can't tell if this also fixes the 3D hangs, but at least, it's a good start! If it also works for others, this should also be applied to the radeonhd driver. Thanks!
I have pulled the git repository and your patch seems to be applied, and it also works for me! Thanks!

Just wanted to confirm that it's fixed. Thank you for the fix.
