[winswitch] testing required: OpenGL client rendering

[Nick Burrett]

With changeset 3053, the visual artefacts remain.  When your suggested
change to gl_check.py, I appear to be viewing the penultimate window update
e.g. if I click on "File", then the background of "File" changes colour,
but the actual File menu does not appear until I move the mouse to the
position of the first menu entry, which forces a background colour change
for that menu entry and the whole menu gets drawn.

Regards,

Nick.
