Anything before that isn’t cleared. Can you find the reason for that? In general, redrawing the cursor should only redraw a single character, and sometimes the two adjacent ones. It shouldn't redraw more than that. >From what you describe, it sounds like the problem is in the logic that determines which parts to redraw, see update_text_area in dispnew.c.
