the flicker is produced by the 'clear()' call (man wclear):

       The  clear  and wclear routines are like erase and werase,
       but they also call clearok, so that the screen is  cleared
       completely  on  the  next call to wrefresh for that window
       and repainted from scratch.

for the effect you're trying to produce, clrtoeol() or clrtobot() would
be better.
