Alas the flicker is still there. Apparently I can't do anything against 
it, it seems to occur during the call to the Qt show() method...

I modified your code, by showing the other window first, and then hiding 
the current one. Theoritically, you should never see the desktop 
background then, as there is always a fullscreen window visible. But we 
see it anyway, so maybe the flicker is related to the desktop composition.

Note that I don't see any flicker with gb.gtk...
