[gtk+-win32] Repainting problem

[Sohail Somani <sohail taggedtype net>]

Hi,

I hope this is the right place to ask about this.

Using GTK+-2.10 on Windows XP, I noticed a repainting bug in one of my 
gtk apps and reproduced it with gtk-demo.exe of gtk 2.10. I've attached 
the screenshot of the problem. It happens when I move the window 
overlapping the gtk app around, in this case mspaint. Note that the 
mspaint titlebar is still visible where it overlapped previously.

Resizing or forcing Windows to invalidate the demo app's window fixes 
the problem. I'd like to know why this is happening and more importantly 
how to fix it or work around it. I think I know why it happens but I'd 
like to be wrong.

Thanks for your time.
