Screenshot from World of Warcraft, showing artifacts with texturing

These artifacts appear on some textures, and change as the character moves
around. The blue bar at the bottom must just be an error in the "screen
capture" process, because it does not appear while playing the game.

I have a Radeon 9550, and am running a 2.6.25.9-SMP kernel with Mesa and DRI
