Screenshot of desktop.

This bug only happens when I enable "MigrationHeuritic" "greedy" with EXA. (This is a Fedora 8 machine, and I am also using the xf86-video-radeon driver from git.) I set the MigrationHeuristic in order to improve EXA's performance, except that now my desktop ends up looking like on the attachment.

I can recreate this effect using both a Radeon 7000 and a Radeon 9550.

This is all with Desktop Effects disabled. The corruption is a lot less obvious if I enable them.
Comment 2 Michel Dänzer 2008-03-18 00:09:53 UTC 
Please attach (as opposed to paste) the full xorg.conf and Xorg.0.log files. Also, if this is with a version of xserver older than 1.4.99.x, please try that.

Comment 5 Chris Rankin 2008-03-22 15:09:02 UTC 
This bug seems to have been fixed by the xorg-x11-server-Xorg-1.3.0.0-44.fc8 package, as compared to the previous xorg-x11-server-Xorg-1.3.0.0-42.fc8 package.

E.g. from the changelog

- xserver-1.3.0-exaupgrade-latest-fixes.patch - airlied - fix EXA
