That's basically because an application that doesn't keep track of the
overlap between windows will try to repaint the whole screen to update
things - that's a lot of output replacing the current contents with itself
and things tend to flash on/off and flicker.  The panel library is designed
to do that (I don't do much with it, but the demos in ncurses seem to do
what they're designed to do).
