Screenshot showing the problems

I'm seeing some 2D rendering problems with the latest radeon git driver, there were some horizontal lines under text in metacity window titles and the firefox address bar, and one or two characters in gnome-terminal became messed up. Using EXA.

If I did git bisect correctly, then fc079c5267baf431bbecee7744e484783d393152 was the first bad commit:

    Don't mix 2D and 3D in the same IB

Does this patch help?
Comment 4 Edward Sheldrake 2008-12-03 08:40:10 UTC 
No, the patch (id 20767) made no noticeable difference.
Comment 5 Alex Deucher 2008-12-03 12:23:58 UTC 
Does
Option "BusType" "PCI"
help?

possible fix

Can you also try this patch? (remove the previous patch)
Comment 7 Edward Sheldrake 2008-12-03 14:04:59 UTC 
BusType "PCI" did not solve the problem but the second patch (id 20769) seems to have fixed it.
Comment 8 Alex Deucher 2008-12-03 14:33:28 UTC
