Uhm, not sure what you exactly mean by Mesa off-screen buffer...? Do you mean
a GLXPixmap? Anyway, keep in mind that rendering to anything else than the 
framebuffer involves pixel transfer which is always slow. You can use 
glXIsDirect() to query if your context is a direct GLX context.

BTW I was maybe a little confusing with my first posting. What a direct context 
does is it bypasses the X server to gain maximum performance.
