There are still too many flickers on macOS 10.13.6.
Steps to reproduce:
1. emacs -Q
2. (setq redisplay-dont-pause nil)
3. Select text across lines with touchpad
I can see blanks and then refreshing, sometimes just a blank retangle without refreshing.
macOS: 10.13.6
Xcode version: 9.2

FWIW that’s exactly what I would expect to happen with that setting
set to nil. We can’t really stop the NS toolkit trying to update the
screen, but if you pause redisplay part‐way through then it’s not
going to be able to update the areas already marked as needing
redrawn.
Once it’s tried to redraw those areas, it marks them as drawn whether
it was succesful or not, so the next time round they will be ignored.
There’s not very much I can do about that.
What’s the use‐case for setting this variable?

Because of a bug for CJK: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=+23412
Can the area be marked as drawn after it be redrawn?

In that bug report you talk about "shaking". Did you mean flickering? Because I don't think I see any shaking in the clip.
In any case, this input method is not from Emacs, right? So I couldn't try reproducing the problem on my machine.

I sent this mail 10 hours ago. But I didn’t see it on http://lists.gnu.org/archive/html/emacs-devel/2019-01/index.html.
So I resent it with another mail provider.

Yes, it should be flickering. The same content is cleared(at the same time, the cursor goes to the beginning of the content area)
and then redisplayed(and the cursor comes back) during inputing.
Yes, the input method is not from emacs. It is provided by the OS.
That bug only happens on macOS. And other apps(including macVim) on the OS don’t have same problem. So it must be a bug of emacs.

The variable redisplay-dont-pause is deprecated. Don't use it.
