I have a very starange problem. I was using Red Hat
8.0, mesa 4 i think, and it was fine.
With RedHat 9.0 mesa 4.0.4, when playing Quake3 or
other OpenGL games, the shadows beneath the characters
and the decals such as blood show thorough the walls.
The shadows seem to be drawn even when they should not
be visible, thus I get an unfair advantage as I can see
players around the corner before they know I am there,
via the shadow.
It may be a Z/W-buffer problem, as the depth may not be
correctly calculated, not sure.
Has anyone ever had this problem before?? Any help is
appreciated. Is it the driver?
Look at the attached picture, RTCW shows the blood of a
dead soldier through the wall i am standing against.
