QVTKWidget doesn't do blocking. It behaves like any other QWidget
when dealing with timers, event loops, and painting.<br>

It should be possible. What happens if you increase the interval on
the timer?<br>
I'm wondering if you're doing something like using a zero interval
repeating timer and Qt is not giving any cycles to anything else.<br>
