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.
Which exact version of Gtk+ are you using? Did you get it from the
oficial zip bundles from ftp.gnome.org <http://ftp.gnome.org>?
