Modifying the MWM hints is how Unity removes the title bar from a window. 
I'm not sure there is any other way to do it.

I did present a patch to the Wine developers which basically checked to 
see if the MWM hints had been modified (by something outside Wine, e.g., 
Unity) and if so, stop Wine from modifying them.  However, the Wine 
developers argued that Unity should not be modifying the hints.  I suppose 
that it is possible that Ubuntu could look into using this patch as a 
delta from upstream.

What I haven't investigated, however, is how things work with Unity 2D. 
Unity 2D doesn't exhibit the double-title-bar problem, but I haven't 
investigated to determine why.
