Instead of flipping windows as in overlay, try openning a new window altogether.

By making a new window you can do a wrefresh(newwin) to update just one
window or wnoutrefresh(newwin) and do everything with a refresh().

The two windows,stdscr and newwin, will be totally independent of each other and
cursor addressing will be dependent on the window addressed.
