Hi, Janek:

Have you thought of turn off compiz-fusion?

Subject: [Yade-dev] [Bug 419861] [NEW] bzr1735 OpenGL + ATI serious problems,ubuntu 9.04
 
Public bug reported:

I am helping Fernando Alonso-Marroquin to get yade running on his PC. He
has ubuntu 9.04, ATI graphics card:

#lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]

#glxinfo | grep direct
direct rendering: Yes

And he is encountering serious display problems. Sometimes everything
works as it should but sometimes:

- only boxes are drawn (either solid or wireframe) and spheres are not drawn at all
- only light source is drawn, and nothing else
- in all cases at least a light source is shown
- drawing Body_ID always works and can be used to reassure the existence of bodies in the OpenGL display

This seems to be irrelevant to restarting yade. Sometimes it does, sometimes it doesnt work just after the restart. The same applies, when closing or opening 3D views, or generating a new simulation. Sometimes it works, sometimes doesnt.
I've never seen such behaviour on my PC.

I have an ATI card lying there, so I will try to reproduce it. I
consider this a critical bug.
