You take the window from the GLX video device (UXGLXDevice or sth.) right?
The glx driver just knows of the root window.

You pure GLX program did work?
I do not have experience with mixing GL with other drawing stuff.
How does XvMC draws its videos? Via Xlib?

Well, I didn't even hope that the fullscreen support works :)
I do not use fullscreen modes and can't remember when I have used
them last time.
IIRC, the fullscreen support is done using the _NET extension of window
managers, i.e. the UFO code stays the same.

Hmm, do you have some sort of a minimal example?
How did you intialize your GLX window in your pure GLX environment?
Atm, I do not know what could be the problem ...
