I haven't seen this exact problem, but I have a few problems with emacs window being slightly the wrong size. For example I have a space between the fringe and the edge of the window in terms of where the scroll bar is placed.  It gets corrupted pixels (as seen below) and never redisplays.  I haven't worried about it because it's only cosmetic, but I mention it now because it might be related. If NSEmacs is calculating the wrong size for the window, courier might get shoved into the mode line.  This is just a wild guess.
