Unnecessary redrawing causes unpleasant flickering that people rightfully complain about. Emacs never writes buffer contents where the mode line should be, so this problem could only happen if Emacs for some reason becomes confused about the window dimensions. The result could be a variety of display problems, not just what you see. Are you willing to debug this problem on your machine using GDB? If so, I might come up with some instructions.
