Public bug reported:

Binary package hint: xserver-xorg-video-ati

[see attached photo]

I see extensive screen tearing and constant waviness. The amount of
tearing increases with increased video action (i.e. running glxgears,
editing a photo in GIMP).

I've tried the following:
Compix off
Kernel nomodeset
xorg edgers ppa drivers
AGPmode = -1 in Xorg.conf

Nothing can get rid of it.

Sometimes I boot and there is no problem at first, but after a few
minutes the screen is unreadable. Screen captures and remote logins via
VNC don't show any problems. ~/.xession-errors and Xorg.log don't show
anything interesting (see attached).

In Karmic and Lucid up to a few weeks ago was fine. I can try older
kernels and see if I can isolate when it started. I've tried what I know
about x debugging, if you need anything else let me know.
