Weird graphical artefacts on OS X Snow Leopard

Since a couple of days I experience some strange graphical artefacts on Snow Leopard. Usually after a certain uptime, the background image would show some strange colours at some place. This could be reverted by reloading the background image. But the problem would appear again after rebooting (and waiting for an indefinite time).

I had the same problem with my MBP. They have documented problems with the NVIDIA cards, but my problem was like yours and not the more popular and widely addressed problem. I had to keep going back to the "genius" bar, and when I finally talked to the head "genius" he was able to test for a "rare" problem, and that was what it was. I have always said, "if you hear hoof-beats think horse, not zebra," but in this case I definitely had a zebra in by machine.
