I think you forgot to attach the screenshot.   But I probably cannot answer
your question, I don't use QVTKRenderWindowInteractor.py very often (I
maintain it because I was one of the initial authors, 15 years ago!), and
on my own system the QWidget base works fine.

to system and driver to driver.  Whatever you discover, please share with
the list.
