I can reproduce the bug in the following configuration:
- Large monitor or small font in terminal.
- Having 2 vertically splitted windows.
- Enable `display-line-number-mode` on the left pane.
- Terminal flickers on scrooling on some lines.

The main point is it flickers only when the right pane has a little
content. If the file contents fits into the whole right window, the it
doesn't flicker, and it flickers only on the lines which do not have
content to display. For example,
--------------------
|        |         |
|        |         |
|        |~        |
| *|*    |~        |
|        |~        |
|        |~        |
--------------------

"~" is the part where there is no content. When I use the left window
and scroll on the lines where the right windown doesn't have content,
the screen flickers. But, as long, as I open some large file in the
right pange it works as expected w/o any flickering.

I tried to find a possible way to put some content in there, but seems
like emacs supports frigne only on GUI.

I tried different terminal emulators (iTerm2, Alacritty), in additional
to w/ and w/o tmux.

The same configuration but with ssh to linux work perfectly well. So, I
assume, it excudes terminal emulator issues.

I also tried different emacs distributions:
 - https://emacsformacosx.com/
 - https://github.com/jimeh/emacs-builds
 - Some with come homebrew as well.

Do you have any possible ideas where I can look into it?
