Changing scroll_screen(x, y); in tests/test.c:hscroll_test() to

if ((x != tx) || (y != ty))
  scroll_screen (tx = x, ty = y);

fixes the problem (though I have also scattered some printfs in
xwin.c).  Maybe display is locked most of the time when scroll screen
is called often, or there is no XSync and X-server is fed up with
drawing requests?
