I put a FIXME comment in xdisp.c redisplay_internal() (line 11551) at  
the same time I made my workaround.  I thought the problem originated  
there, but wasn't certain enough to pursue it further.   
(consider_all_windows set true causes each FRAME to be temporarily  
selected in turn later in this function.)

Since the problem seems to be gone, I'll take a look through the  
history once savannah is back to see what might have changed.
