A screenshot showing the problem this bug is about: You can see parts of the
panel shining though while the window should be maximized

I am using KDE 4.7 as desktop environment, and I set up the plasma panel to
stay below windows. I also configured KWin to remove the title bar from
maximized window. This way, no precious space is wasted on my 15 inch (laptop)
screen for title bar and panel which I rarely look at, and the whole space can
be sued by the application for whatever I am actually doing right now.
However, wine can not properly cope with this configuration: Maximizing a wine
window leaves a space of 15 pixel below the window where I can see other
windows behind it (see attached screenshot). Since maximizing is working fine
for non-KDE apps like Firefox. I tried regedit and a Windows application I
wrote myself, both showed the same behaviour. This leads me to the assumption
that this is not a bug in KWin or some Windows application, but in wine itself.
