--- Comment #23 from Severin Strobl <fd at severin-strobl.de> ---
Forcing the complete redraw eliminates the problem, of course at the cost of
increased CPU load. For some strange reason, with deactivated full redraw I
encountered the image corruption only extremely rarely today. I was able to
reproduce it twice after trying for several minutes. It was with a different
external screen (resolution), so I'll try again this evening with the setup I
used on the weekend.
