bug#57434: 28.1.91; Terminal Emacs Mac OS flickering.

[Dmitrii Kuragin]

Sorry, I completely misunderstood it. 

I actually wasn't able to reproduce flickering on Terminal.app, only on Alacritty.

I need a bit more rest :)

Thank you for digging deeper into this! There is a lot of useful information. But,

Here's a video of flickering https://youtu.be/Is2ebMXjhxg:

 - Different MacBook (2019 I believe).

 - Terminal.app (The one which comes as a standard).

 - Simplest Emacs from http://emacsformacosx.com/

 - No tmux.

 - No advanced user customizations (it is not my laptop).

 - Only display-line-numbers-mode is enabled with 'visual type.

It is definitely not attached to Alacritty, but probably the same issue with refresh vs frame rate updates.

Exactly.  I don't think it's reasonable to expect users to figure out
what and when to send if we cannot figure that out ourselves.
