The new NS port still shows excessive redrawing while resizing frames  
(with the mouse); the window contents are drawn about one line too  
low  before they are redrawn again in the right spot.  This animation  
takes place every-time the mouse cursor is moved a bit, so we're going  
to a lot of animations while a frame is being resized.

Enabling the tool bar leads to a minor extra redisplay, slightly below  
the target position.

Maximizing a frame leads to multiple extra redisplays, at first with  
all elements (e.g., mode-line) in their old locations before the frame  
is cleared and redrawn.

I checked in a small change to EmacsView-drawRect: that eliminates  
some of the off-target redisplays at least.  At least some behavior  
must be different under Tiger and Leopard, as on Tiger no redisplay  
gets triggered during resize unless the window is dragged a full grid  
increment.

Ah, good, thanks, ignore part of my earlier e-mail then.

I can't reproduce any slow redisplaying on Emacs 24.5 or 25.1 under El
Capitan, in fact it just doesn't redisplay at all until I let go of the
mouse button. I guess this means either this patch, or some subsequent
work, fixed this bug, so I'll close this as fixed.

I could never reproduce this and no one else was able to fix it, so this feature was removed.  The bug can be closed.
