G'day Lars, Unfortunately it appears that nobody has worked on your bug. I am not the most knowledgeable person in this area, but I recall reading that there were some fence-related fixes for ATI graphics hadware in later kernels. Does this still occur on Ubuntu 10.10 "Maverick Meerkat"? What about on Ubuntu 11.10 "Oneiric Ocelot" with Unity 2D?
