That's right. That's why I asked in the dri lists. I previously posted a
similar mail in debian-powerpc and Michel D=E4nzer suggested that the
problem could be DRI specific. I also have a nVidia card and everything
works well there.

As Brian says, glPushAttrib() seems to bring OpenGL to an undefined state.
=46or instance, I have some lights in the scene which are positioned after
camera movement so if I move the camera the lights remain pointing to the
ground; then I have some objects pushing the GL_LIGHTING_BIT which causes
the lights to be displaced as the camera moves, weird. If I don't use
glPushAttrib() the scene renders properly.

The GL_CURRENT_BIT doesn't work either, color is not well restored after
glPopAttrib().

Well, I guess the explanation is not quite clear. I could write a sample
program to test glPushAttrib() if you want.
