I tried with a fresh WINEPREFIX and it does not happen, it only happens if "Allow the window manager to decorate the windows" is not ticked.
Hmm, having done a little test on OS X now, and it seems to work with the option enabled and disabled. I don't currently have access to a Linux box. What window manager are you using?
