Since, I got no reply for this, I have prepared a small test case. It is a
dock/undock example from Qt and I have just added QVTKWidget to it. Atleast
the flickering should be disabled somehow. Can some experts help me?

I am using Qt 5.5 and vtk 6.3. This happens only on MAC (tested on OS X
Yosemite & OS X El Capitan).
