[Problem]
With compiz _on_ I get wild screen corruption when doing anything like flipping workspaces. With compiz _off_ the same effect happens when running a simple python opengl program.

[Original Description]
I've seen this with compiz on and off. With compiz _on_ I get wild screen corruption when doing anything like flipping workspaces. With compiz _off_ the same effect happens when running a simple python opengl program. Will attach a video taken with my phone mp4 format, hope you can play it because the ogv version made using ffmpeg2theora is vastly accelerated frame rate, but does show the issue. Also will attach the python code which causes the issue.
