--- Comment #7 from Sean Pryor spryor@redhat.com --- Oh, all of this was performed with CSMT enabled. The game really isn't playable without it due to numerous graphical glitches. I tested just now and yes this issue does occur without CSMT as well.
With CSMT and strict draw order the fog textures and other things work properly, but the performance suffers. With CSMT and without strict draw ordering the performance is better, but there are graphical glitches with the fog and other background textures like that
