[Problem]
X displays various artifacts, dots and white lines all over the screen, same
effect whether XAA or EXA is enabled.  (EXA also causes a freeze).

Reported against Jaunty originally but confirmed to still happen on Karmic with
a recent git snapshot of -ati.


[Original Description]
See attached screenshot.  Dots and lines start appearing right after X starts. 
After a while (usually a day or two), entire areas of the screen start filling
up with flickering lines.
Note that my xorg.conf has XAA enabled because EXA causes X to lock up (bug
#345224), but I've tried switching back to EXA and saw the same artifacts in
the short time before X froze.
