Updated version of Henri Verbeet's hack with minor fix

I attached an updated version of Henri Verbeet's hack (which I can confirm
solves the problem for me). I had to change one line to make it compile with
the current Git master (b09d195bf3c1bd4fef208411ffdbd31b4f1031c). Also I added
code to exclude hidden windows from the clipping mask because you do not want
to obscure these.

Is there any chance this (or a similar solution) will be integrated into Wine
anytime soon?
