No, you are not supposed to be using -mwextwm nor -multiwindow.  Both of 
these parameters are intended to be used with a Windows-based window 
manager; -multiwindow starts this window manager automatically while 
-mwextwm relies on you to manually launch "xwinwm" (available in the 
xwinwm package for Cygwin) and since you are probably not launching 
xwinwm you are not having problems with trying to run two window 
managers in that case.

You need to be using either -rootless or -nodecoration (try each and 
decide which you like).

You may also be having a little trouble if you are using Cygwin's 
OpenSSH with "ssh -X", in that case you need to switch to "ssh -Y".
