Description Ralph Loader 2005-08-07 14:29:39 UTC
Using a radeon 9550SE (detected as 9600) with Fedora xorg-x11-6.8.2-45.i386.rpm
running at 2048x1536 the background image is corrupted:

* it seems to get redrawn with the content offset by a random horizontal &
vertical amount.

* copies of the onscreen windows appear in the background image.

The actual window contents appear just fine.

Guessing as to the problem, it looks like the background image is being kept in
the video card ram but the wrong part of video ram gets copied to the visible
screen.

Same system is just fine at 1920x1440.

Also happens with xorg-x11-6.8.99.14-3 binaries downloaded from
ftp://people.redhat.com/mharris/testing/unstable/
Comment 1 Ralph Loader 2005-08-07 19:27:11 UTC
Errr... I was incorrect about what versions / resolutions the problem occurs
with (it helps to restart the X server!)

The bug happens at all resolutions with 6.8.99.14 and never with 6.8.2.
Comment 2 Pawel Worach 2005-08-25 10:33:00 UTC
I'm not sure if I'm seeing the same issue, using xorg 6.8.99.12 on FreeBSD
7.0-CURRENT with an "ATI Radeon Mobility 9000 (M9) Lf (AGP)" card. It also
causes problems for various gnome games like Blackjack. Screenshot of desktop
background problem coming up.

This also happens with the nv(4x) driver so it's not radeon specific, I'll leave
the component as-is since I have no idea what to change it to.
Comment 5 Pawel Worach 2005-08-28 16:29:31 UTC
I did an attempt at a binary search and found that even the 6.8.99.1 snapshot
presents this problem. I'll continue the hunt with cvs checkouts between
February and April.
Comment 6 Pawel Worach 2005-09-18 08:12:05 UTC
I can no longer reproduce this problem with a CVS snapshot from today.
Comment 7 T. Hood 2005-09-23 05:49:36 UTC
Changing component to Server/general for now.
Comment 8 Ralph Loader 2005-12-24 08:10:49 UTC
This works for me in the 7.0 release.
