I’ve got problems with an app written for SGI : Colors don’t come correctly. From time to time (!) the window raises with junk colors and no Z-buffer at all. My config is :
Red Hat 6.2
NVIDIA TNT2
Mesa 3.1
X11 and glX for window features, OpenGL of course…
I choose an RGB - Doublebuffer visual, and can’t find out why colors are not correctly set.
Meanwhile I read the Mesa doc (sorry for posting a documented topic!), and the pb comes from the glXchooseVisual fn : under Mesa, it returns all sort of Visuals even if we ask for an RGB one.
