Red Hat Bugzilla – Bug 213977
OpenGL program windows display oddly and leave old frames behind when compiz is on.

Description of problem:
Compiz doesn't show OpenGL program windows correctly. Disabling compiz makes
the program window display correctly.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enable desktop effects. Install Celestia (or use any other OpenGL program
you can run in a window). I'll use Celestia for this example.
2. Open Celestia. Notice how the program doesn't render smoothly.
3. Move the window around.
The old frames are left behind.
The window's OpenGL would work normally and the desktop effects would "wobble"
the window if that's enabled.
No OpenGL program I've seen works well when compiz is enabled. I understand
that compiz uses OpenGL to do its work, but it seems like there's some serious
problem using OpenGL to transform the windows in real-time as compiz does when
that window has OpenGL output.
I have the same problem (with glxgears).
I also have the same problem playing videos, see:
and i have an intel dg965wh motherboard with a g965 video chipset.
