with latest ddx/mesa/drm i get strange rendering color problems only with cairo engine used by firefox for example. if i go to a site with offending colors (like padoca.wordpress.com), the grey/cyan background is rendered almost black instead of the pattern, and i get A LOT of this in syslog: Jul 6 14:49:52 kerberos kernel: [ 6933.106204] [drm:r300_cs_track_check] *ERROR* [drm] No buffer for color buffer 0 ! Jul 6 14:49:52 kerberos kernel: [ 6933.106209] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! and by a LOT i really mean a LOT :D xorg is xorg-server 1.6.99.1+git20090705.fd4eed69-0~padoka1 (groo@kerberos). best regards

Does Option "EXANoComposite" work around the problem?

I think that was a regression in pixman 0.15.x which should be fixed in 0.16. So the problem only happens with KMS, right? Does it not happen when booting without KMS even using the same driver binary?
I've just updated pixman to latest git, and recompile xorg-server but no change, same corrupted background
(In reply to comment #9) > I've just updated pixman to latest git, and recompile xorg-server but no > change, same corrupted background That paragraph was only referring to the problems with ExaNoComposite.
Oh my, the patch had the dst/src pictures reversed in the PrepareComposite call... Fixed now in commit 794ae743c305331741e7cf45dd71c755fe325ed5 .
i can confirm it fixed the bug, thank you very much :)
