Well, it would be more helpful if you actually could explain the problem and 
how you fixed it, and what are the issues to keep in mind with the Windows 
port.

I don't know why this patch fixes the problem for you; however, the docs say 
it is not necessary to call painter.end() since the painter destructor does 
that automatically.

So the end() in the background() method should not be needed. Is it really 
needed to see the results?

If it is so, this would mean that Qt on windows queues the commands and 
performs them only on end(). But this is not clearly needed by reading the 
documentation.
