Description Pierre Ossman 2006-04-25 21:51:26 UTC 
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.

Screen shot of vncviewer getting jiggy with it (ThinLinc is a flashy packaging
of it).

Comment 5 Ilya Konstantinov 2006-04-25 22:43:05 UTC 
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).
Comment 6 Michel Dänzer 2006-04-25 23:03:44 UTC 
Does the patch from
http://lists.freedesktop.org/archives/xorg/2006-April/014919.html help?

(Are you guys both running Fedora Core?)
Comment 7 Pierre Ossman 2006-04-26 00:03:59 UTC 
I am running fedora yes.

I'll test the patch as soon as I've tested the latest ideas for bug 4668.
Comment 8 Eric Anholt 2006-04-27 09:33:23 UTC 
I would guess that this is bug #6755, but it's not totally clear.
Comment 9 Pierre Ossman 2006-04-27 21:44:13 UTC 
Tested the patch in comment 6, but it had no effect.
Comment 10 Pierre Ossman 2006-04-27 21:51:44 UTC 
It would seem this is bug 6755 yes. Turning of DRI or tiling makes the problem
go away.
