As you can see in the pic, there are quite a few missing textures. These actually flash rapidly between the normal textures and no textures. It normally happens to the sky or if a map has rain like in ramel for urban-terror, the whole screen tends to flash. I have no clue what the problem is. America's Army, Tuxracer, and GLtron run without issue. I'm using a radeon 8500 128mb with the fglrx driver. I'm running redhat 9(2.4.20-20.9).
