Colored problems ...

[Anne-Gael]

Hi !

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.

Any idea would be great, thanks ..

Can you post the code you used to create the window and the visual? It may be something as simple as not setting the size of the color buffers.

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.

Thanks for spending time.
