screenshot of the problem

When I switch from a virtual desktop to one with Lotus Notes running on it
(with wine), the content of the window is not always displayed. Instead, the
content of the window is a "dead zone" where, at first, the content of the
previous desktop is displayed then everything that is displayed there is keeped
in the window.

See the screenshot for the explanation.

I launched Gedit and Gnome-terminal on one desktop (you can see them remaining)
then I switched to the Lotus Notes desktop. Then I opened the main menu to take
a screenshot and the menu image remained in the "dead zone".

The workaround is to switch to another desktop and go back. After two or three
times, it should work.

This bug is a regression that came with Wine 0.9.57 (and the "Many window
management fixes." changelog.. hem). It was working perfectly in 0.9.55 and in
0.9.56 (but I didn't use 0.9.56 for a long time).
