KWin treats them identic to dock windows (WRT decorations).

Menubar? You mean titlebar?

It is honoring it, but I don't think it is using it. In KDE, the tearoff menus 
are used as offered by Qt, which transforms them in normal windows when 
tearing them off, thus they automatically get decorated properly.

I don't have enough experience to realize if decorating TYPE_MENU windows 
would wreak havoc anywhere. I fact, I now wonder what is the purpose of the 
TYPE_MENU spec in the NET protocol (i.e., what were the reasons for which it 
was specified). And I also wonder: is a menu gets decorated, what 
differentiates it from a normal window? Why does it need/require the 
TYPE_MENU hint on it?
