Comment 7 for bug 204238

I'm having what appears to be a Qt4+OpenGL+compiz problem too.
The Qt4 application is something I have written which uses
multiple OpenGL windows within a single widget,
sharing display lists. Typically
what happens is that the CPU goes 100% for a few seconds
when I do things with the OpenGL windows like minimize one
(so that the others have to resize etc)

When I turn off compiz everything is well-behaved.

I am using:

Linux pooter 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux
/usr/lib/libQtOpenGL.so.4.3.4
OpenGL version string: 2.1.2 NVIDIA 169.12
