hi, the kde4 desaturates the desktop when displaying logout dialog. with current radeon driver (git describe: xf86-video-ati-6.13.2-93-gfadee04) it looks broken.
Created attachment 42328 [details] screen before logout.
Created attachment 42329 [details] damaged fade-out.
I had similar behaviour on my HD4350; it was fixed by the current Mesa/X in the Ubuntu xorg-edgers set (I'm on Ubuntu): mesa-common-dev 7.11.0+git20110119.a5da4acb-0ubuntu0sarvatt libdrm-radeon1 2.4.23+git20110119.550fe2ca-0ubuntu0sarvatt The Xserver is still xserver-xorg-video-radeon 1:6.13.2-1ubuntu2 I'm not sure which thing fixed it however; Here's my bug report: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/694480
Pawel please test more recent mesa/ddx driver Also please try r600g
(In reply to comment #4) > Pawel please test more recent mesa/ddx driver > > Also please try r600g i've tested current xf86-video-ati-6.14.0-41-g6319a33 with mesa 7.11 (snb-magic-2482-gdedc81e) and the default r600 is still broken while r600 gallium seems to work fine (kde effects, quake3).
Can confirm the same distortion with classic r600 (HD5870M mesa 7.10.2 + xf86-video-ati 6.14.2). No more distortions after switching to gallium r600 however.
I think this problem was fixed in a recent update. I've been experiencing it for a long time but not any longer. The fix probably went in some time during the past few months.

Resolving this report as WONTFIX as the classic r600 driver is no longer being developed.
