screen doesn't clear/redraw properly when hierarchy is taller than window

[bjarthur]

i have an array in a dict in a dict in a dict. the first couple times i expand the redraw occurs on top of itself, but eventually the hierarchy is taller then the window, and then there is a bunch of repetition. this is with GNU bash 3.2.56 on mac os catalina and julia 1.5.
