Public bug reported:
I have two screens connected to my machine, and I run them side by side.
A few times per day, the secondary screen breaks down into a flickering
jumble. Usually the screen contents is still visible, but like on an
old TV that's gone out of sync. The background is definitely there, you
can see a few instances of every window, and the mouse pointer is
visible in a few places as well.
The symptoms tend to pass if I manage to move any windows away from that
screen so that it shows only the background.
I'm not seeing any crashes or any other symptoms.
This happened in Jaunty, and it is still happening in Karmic.
