Then this may be caused by Qt itself which maybe tries to emulate a non-supported openGL feature for your card..

I discovered a clue to the nature of the resizing problem I have.  Resizing
the application window and making it _smaller_ than the original size is no
problem.  I can then resize back up to the original size without an impact
on th frame rate.

As soon as the window is re-sized to bigger than the original size, I get a
very poor frame rate.

This does recover when I resize back to the smaller size.
