I'm afraid I wouldn't know where to begin to debug this.  My primary problem
is of course that I don't have a MacOS X machine at my disposal.

My first suspect would be the vtkFlRenderWindowInteractor::draw() method.
The code as it is now works on X and Windows.  I never had any opportunity
to check this on MacOS X though.  If I were you, I'd start by checking that
the Fl_Gl_Window works perfectly on your system: you should be able to find
a simple FLTK example that helps in this regard.  After that, have a look in
the source of the vtkCocoaRenderWindow and the vtkCarbonRenderWindow.

I would love to hear of any progress that you make.

Best regards,
Charl
