That's what I get when using GLX Pixmaps (using pBuffers gives me an
GLXUnsupportedPrivateRequest error).

I'm curious as to whether or not either of the off-screen drawing
methods have ever worked for anyone. It's entirely possible that the
new GLX context isn't being initialised correctly.

The rather haphazard design of the OGSF library and the lack of
substantial documentation make it less than straightforward to
determine what (if anything) needs to be done when rendering to a
different context.
