This sounds like a bug in the XAA acceleration architecture, which is
resolved by specifying AccelMethod EXA in your xorg.conf. Note that in
Intrepid EXA has some performance regression compared with XAA, so it
may or may not be worth switching, but for Jaunty, EXA performance is
much improved,

I have an ATI RV280 based ASUS 9250 AGP graphics card and I am using the
radeon driver.
With the Xorg version used under Ubuntu 8.04 I had no problems and a
good X11 image display.
After upgrading to 8.10, I noticed that the X display occasionally shimmers,
and that there are severe worry lines
This is still happening on resume from hibernation in Jaunty Alpha 6.
Screenshot attached shows what happens after switching to console 1 and
back to 7.

[Intrepid] Screen artifacts on
I am also seeing corruption in Jaunty, only when resuming from
hibernation (very similar to this bug:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
ati/+bug/293395 ).
Hardware is Acer Ferrari 3000 with a Mobility Radeon 9200 (r200). This
happens with and without compositing
Hi!
Can anybody confirm that the workaround in bug #293395 solves this
issue? (In this case I'd mark this report as a duplicate of #293395).
Thanks for your support.

I just added
Option AccelMethod exa
to the device section of my xorg.conf and it seems to have fixed my corruption
issue. YMMV of course.

see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-driver-
ati/+bug/293395, i think it might be the same bug. The workaround
definitely fixes this for me. Therefore I think this is an xserver-xorg-
driver-ati bug.

Same issue here on a HP nw8440 with a Mobility FireGL v5200. Window
boarders disappear or get corrupt after resume.See corruption on the
leftmost terminal window in the attached picture.

I have about the same problem as Steven Dee reported it (see
corruption.png) on a Radeon 9600 (Inspiron 8600) and using the standard
drivers.

I have about the same problem on a T60p with FireGL V5250 and using the
standard drivers (radeon) on Intrepid. Upon resume I get bars of
corruption below the upper gnome panel and above the lower gnome panel.
I can post a screenshot later, it is 100% reproducable.
Sadly, fglrx won't let me
An example of the corruption; this is a screenshot of the desktop wall
post-resume. Note that the random choppiness towards the top is just a
result of switching desktops to bring up the wall; the interesting
portion is just the white blocky weird crap in the center of the screen.

Another example.
