The first and last ones aren't GLX functions, they're standard OpenGL
functions, so it isn't just GLX that's the problem.

That can only be a Tk error. It's almost impossible to say what the
problem is; BadMatch can mean just about anything:

       BadMatch  Some argument or pair of arguments has the correct type and
                 range but fails to match in some other way required by the
                 request.

IIRC, X_PolyFillRectangle corresponds to XFillRectangles, which most
GUI toolkits use extensively.
