Sorry, I just realised I used the normal X server last week instead of git. But that doesn't change the issue. Setting XaanOffSceenpixmaps to true solves it. Created attachment 18177 [details]
my current xorg.cong
Currently I expereince this bug always when I enable exa: The screen flickers at the whole right in some cases:
* switching from workspace
* scrolling in a non-maximized window
* running gtkperf
* and more..
I use compiz as window manager and have a X1300 card.

Using: drm modules from 2008 08 03 xserver-xorg-video-ati: from xorg edgers version git20080802 |

Created attachment 16864 [details] Xorg log Xorg log reports: "(EE) RADEON(0): Unable to reserve offscreen area for back buffer, you might experience screen corruption". I notice indeed some screen corruption in the right area of my screen. One week ago I saw them only with exa enabled in my xorg.conf. I'm using the xorg edgers packages of 06-01-2008 on ubuntu hardy.
