Forgot to add. There's a 2nd issue that I'm curious if you can see also:
When the 3D model is drawn, scale numbers are drawn along the axis.
(-10, -5, 0, 5, 10). With VGL or even with some plain remote X servers
those numbers are drawn with black boxes. If you run on local console
you'll see the numbers. (I'm currently trying to track this down; the
real numbers are drawn to a pixmap via X RENDER extension, pulled in to
GL textures where I see good data, and then drawn to the GLXPixmap.)
