test case
I noticed problems with materials in my game - for some reason the whole scene
is rendered with one color. After some experiments I found that this is first
color passed to the glMaterialfv.
I thought it's problem with my game, so I wrote simple program which renders
two quads - and problem still exists there. I tried with hardware acceleration
(r300) and without it (LIBGL_ALWAYS_INDIRECT) - in both cases everything was
rendered in one color.
So I tried fglrx - and it worked correctly - there are different colors after
each glMaterial call. So I believe there is a bug in Mesa.
Problem doesn't exist when using GL_COLOR_MATERIAL (which is probably the
reason nobody found it before). Problem doesn't exist when using display lists.
Problem doesn't exist when using gluBeginSurface/gluEndSurface (probably it
clears some state).
Please compile attached test case with:
g++ material.cc -lSDL -lGL
On Mesa you will notice two rectangles with same color, on fglrx you will
notice two rectangles with different colors.
