Running on dapper amd64 with a radeon 9250 (from tungsten, same problem occurred with the ati 9200 card, which works normally on another machine under dapper32)
Apps using opengl acceleration work, but if the window loses focus. The image splits in 1/2, and seems to draw only on the left edge of the screen. Going to fullscreen and back solves it. Problem is easily reproducable, and gives no sort of error output when it occurs (AFAIK).
Here are some example screenshots (occurs with other apps that use opengl too, like glxgears, flightgear, dosbox (if it's set to use opengl) etc.:
Then it's normal after going to fullscreen and back.
The warnings when running an opengl app:

Ok I'm pretty sure this is a software issue.
