I agree that it's most likely to be a bug in pygame, but it could be
somewhere in wxPython or possibly within Windows.

One serious issues with GLUT is that you relinquish control to its
mainloop.  I think wxGLCanvas would be the same. Another historical
reason for choosing pygame was the promise of support for multiple
screens, which hasn't materialized (but workarounds are available).
