Neither.  There's a reason why Qt4 is still called "beta".  It has bugs in it and missing features.
In your case, it is a bug in Qt4 on Windows.  Your app works perfectly fine under X11 using Qt4.
I have a simple app which demonstrates the problem that I'll give to trolltech.  This simple app doesn't use VTK or QVTKWidget.
