pygame has a function to control extra setting for opengl. it must be
called before display.set_mode(). you'd probably want to pass something
like "pygame.display.gl_set_attribute(GL_DEPTH_SIZE, 16)". perhaps try
different sized depths?

you might also try testing with GLUT, which usually builds with pyopengl.
