It did work for me before. For anyone else who finds this bug report and has the same problem, what worked for me to bring back the old behavior (fullscreen virtual desktop window, drawn above any menu bars, doesn't get resized on resolution change) was adding these config options to your window manager like Henri said. Here are the config options for Compiz:
Window Decoration: !(class=Wine)
Window Rules: Fullscreen: class=Wine
I don't quite follow there. Making that entry under Window Decoration prevents wine getting resized, but when I launch certain games, ie "Dogfighter", the Unity panel at the top of the screen shows over everything. The Window Rules entry doesn't seem to do anything about that.
