Public bug reported:
Binary package hint: xserver-xorg-video-ati
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.
