1 Hi,
2
3 I'm having some problems with a simple OpenGL program (as described
4 here: http://forums.gentoo.org/viewtopic-t-464101.html) which is
5 supposed to render a small red sphere inside a larger wireframe one.
6 It seems that when I switch the order of the OpenGL calls to render
7 them it renders the wireframe sphere as filled.
8
9 The problem also appears if I run the FOX toolkit "glviewer" test and
10 set the rendering mode to wireframe.
11
12 Other OpenGL programs (e.g: glxgears) seem to be fine...
13
14 Can anyone confirm (or not) that this happens on their system as well,
15 please? Possibly this is a known problem, but I couldn't find any
16 references to it elsewhere on the web.
17
18 Also, if anyone can suggest a fix, I'd be very grateful.

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

23 Thanks,
