Subject: glPolygonMode rendering problems
Date: Fri, 26 May 2006 17:29:08 +0100
Hi,

I'm having some problems with a simple OpenGL program (as described 
here: http://forums.gentoo.org/viewtopic-t-464101.html) which is 
supposed to render a small red sphere inside a larger wireframe one. 
It seems that when I switch the order of the OpenGL calls to render 
them it renders the wireframe sphere as filled.

The problem also appears if I run the FOX toolkit "glviewer" test and 
set the rendering mode to wireframe.

Other OpenGL programs (e.g: glxgears) seem to be fine...

Can anyone confirm (or not) that this happens on their system as well, 
please? Possibly this is a known problem, but I couldn't find any 
references to it elsewhere on the web.

Also, if anyone can suggest a fix, I'd be very grateful.

See below for my hardware/software setup. If anyone wants screenshots 
I'd be happy to provide them.

Thanks,

Matt
