description:
Pads are not to be automatically refreshed on input.

X/Open Curses says in the documentation for newpad():

  Automatic refreshes of pads (e.g., from scrolling or echoing of
  input) do not occur.

And in the documentation for get*():

  If the current or specified window is not a pad, and it has been
  moved or modified since the last refresh operation, then it will be
  refreshed before another character is read.
