patch 9.2.0228: still possible flicker

Problem:  still possible flicker
Solution: Use redraw_as_cleared() instead of screenclear() to avoid
          flicker (Yasuhiro Matsumoto).

When the window width matches the frame width, screenclear() causes
visible flicker. Use redraw_as_cleared() instead which marks the
screen for redraw without actually clearing it.
