Render bug

[Chien Yang]

This looks like a bug in JavaFX when applying the lighting effect. I was 
able to reproduce the dirty rect rendering on my system. The bug went 
away if I commented  out the following line:

        iview.setEffect(lighting);

Can you please file a JIRA so that we will fix it?

Thanks,
