Test app I can not give unfortunately.

Concerning the problem I did some more testing by directly parenting the
window while creating it. The problem persists so it does not seem to be
a parenting problem but a general problem of adding an opengl enabled
window to a foreign window. In my case this is FOX-ToolKit and
NPAPI(firefox). With FOX I could remedy the problem with some
unnecessary resize spaming but in the NPAPI case I could not get it
somehow working yet. I think the resize spaming is also more fixing
symptoms instead of the real problem but I just can't figure out how to
debug the problem. It has to be somehow connected to OpenGL visual
created window and compositing which itself does crap application
windows with OpenGL. Maybe compositing gets confused by the X events
somehow?
