Some applications trigger rather extreme framebuffer corruption when using EXA. Most notable sinners are Flash and vncviewer. I only recently decided to try EXA again so I don't know when this appeared. Somewhere between the 7.0 rc:s and today.
Created attachment 5470 [details] Screenshot Screen shot of vncviewer getting jiggy with it (ThinLinc is a flashy packaging of it).

On Radeon 7000/VE (AGP) with EXA and a recent CVS version of the driver, when running windowed VMware Workstation session, the hosted session's display image is corrupted in the same way (smears a lot beyond outside the boundaries of the VMware Workstation window).
Does the patch from http://lists.freedesktop.org/archives/xorg/2006-April/014919.html help? (Are you guys both running Fedora Core?)
I am running fedora yes. I'll test the patch as soon as I've tested the latest ideas for bug 4668.
I would guess that this is bug #6755, but it's not totally clear.
Tested the patch in comment 6, but it had no effect.
It would seem this is bug 6755 yes. Turning of DRI or tiling makes the problem go away.
