It appears the full screen thing makes the difference.  The reason why, 
I'm not sure.
Delayed initialization is done by getting the polish event.  But in this 
case, the resize appears to be done after the polish event.  I expect 
the resize to be before the polish.
It behaves the same whether it is a normal QWidget or the QVTKWidget.
So I suggest you take your question to the qt interest list, and ask 
them for more information or for a solution.
