Hi

I have somes problems with the Matrox G200. The UV coor are wrong on the 3/4 of the polys. The bug is G200 specific and does not appear on others cards like nvidia, permedia, 3dfx...

Thank to all. Your help is very appreciated.

I found that the problem is with glTexCoord4f.

problem with G200 when (working on others cards):
glTexCoord4f( u/z, v/z, 0.0f(or 1.0f), 1/z);

but when I specify wih G200:
glTexCoord4f( u, v, 0.0f(or 1.0f), 1/z);
The tex coor is ok but no perspective correct.
