I understand that this is precisely what is currently done. Insofar as
it behaves as documented, it is not a bug in that respect.
But, as I have mentioned before. This behavior makes it exceedingly
painful for a user to switch back and forth between two different
monitors viewing different areas of the map. I think things should be
changed so that each monitor keeps track of its own region independent
of "the region" in GRASS.
To phrase things in terms that must be considered a non-feature if not
a glaring bug, think about this sequence:
d.zoom # zoom in a bit interactively
Clearly, at this point, the overlay data will not be properly
displayed on monitor x0. I can't see any reason to justify this
