I now know that this is a graphics driver bug (there is a tiny possibility that i could be caused by damaged/faulty video hardware, but I doubt it). It will need a fix by the upstream developers, most likely in the linux kernel or possibly in the xserver-xorg-video-ati package. Unfortunately I have noticed that very little development is done anymore on the drivers for the Mobility Radeon 7000 and similar cards, probably because they are so old.
