[Qt-interest] OpenGL Refresh Issue

[Willy P]

Hey,
I'm upgrading from 4.5.3 to 4.6.3 and I'm having some OpenGL issues.
Rather than explain it, here is a 30 second video showing what
happens:

I click in one widget, then click in the GL widget and get a white
screen until I move the mouse.

What advice would any of you give me for debugging this issue?  I know
you probably won't know exactly what's going on, but my current
strategy is not working and I'd be very appreciative of any
strategies.

Thanks so much...
