@ Christoph Korn:
That is just the kind of display errors I get, albeit not that often...
@ All:
Installing 180.11 drivers makes the situation better for a while, but I did experience some errors when compiz had been running for a long time (and only on my external screen (my computer is a laptop), which had a higher frequency of errors earlier). Restarting compiz (alt+f2 -> compiz --reload, I need to do that twice compiz crashes the first time and fallbacks to metacity) fixed the problem.
