[vtkusers] Java vtkCanvas/vtkPanel blank on start up, have to manually resize to show content

I am trying to figure out how to display content of Java's vtkPanel at 
startup (or vtkRenderWindowPanel). Consider JFrameRenderer example at 
http://www.vtk.org/Wiki/VTK/Examples/Java/SwingIntegration/JFrameRenderer

When I started the frame it is correctly sized, for a moment the content 
flickers then goes blank. It can be displayed by resizing the window or 
simply pressing 'R'. Similar thing may happen when the frame is 
minimized, after it is restored, content may be blank (it intermittent, 
though frequent); pressing 'R' restores the display.

Any ideas how to get the display right when frame opens?
