Description J.B. Nicholson-Owens 2006-11-04 06:10:36 UTC 
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):
compiz 0.0.13

How reproducible:
Every time.

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.

Actual results:
The old frames are left behind.

Expected results:
The window's OpenGL would work normally and the desktop effects would "wobble"
the window if that's enabled.

Additional info:
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.
