I tested, it doesn't help. Further testing revealed that the 91.73
revision of the NVidia drivers can not draw onto windows that are owned
by another process.
Disabling hardware acceleration completely makes it work though.

None of these were reproducible when I disabled hardware acceleration,
only problem was that it was very slow.
I have the feeling that we hit a whole nest of driver bugs here...
(actually I am not sure in how far it is supposed to work, and if the
Windows graphics stuff is actually thread-safe at all, but the fact that
disabled hardware acceleration makes it work for me sure looks like a
bug).
