I tested Warcraft III with KDE, IceWM and XFCE (and initially GNOME) : each times, this bug happens. So I think it's pretty sure it's not a WM bug.
Pretty much strange conclusion. To me it looks like that according to your test none of the WMs above support X11 processes running in different screen modes.
Why this could not be a bug of Wine ?
Due to the reasons already explained in this bug.
