I’ve pushed a slight variant of this change to emacs-26. I’ve
witnessed a very rare flicker of the modeline and the line containing
the cursor in other windows while scrolling, but I can’t replicate it
consistently.
I opened a large file (xdisp.c), set the frame up like so:
M-f10 C-x 3 C-x 2, and scrolled the top left window up and down as
fast as possible.
Thanks for your help with this.
