Hi everyone.

I'm trying to draw a simple glTriangle as an overlay into a
Performer-Channel, doing this in the DrawChannel-callback after having
called pfDraw(). It works fine on Windows, while on Linux, I don't see
anything of my triangle.
Could that be some kind of display-driver/openGL-version problem (both
machines have NVidia graphic cards)?

Besides I'm having problems generating mipmap textures using
gluBuild2DMipmaps() on Linux. The app segfaults whenever this function
is called. Again, everything is fine if I try it on Windows. I found a
posting on Info-Performer from May 2002 describing a similar problem but
with no real solution.

Any sugestions?
