Subject: 29.0.50; column-number-mode causes point to jump around
Date: Fri, 26 Nov 2021 15:50:52 -0400

If emacs is started with:

emacs -nw -q -l /home/jrm/.emacs.d/custom-lite.el blah

with custom-lite.el only containing

(custom-set-variables
  '(column-number-mode t))

Then typing characters will cause the point to move around in unexpected
ways.  For example, when typing

12345678

into the scratch buffer, after the 8 in entered, the point is moved back
to the second column (over the 3).

I cannot reproduce this.  Does it happen with "emacs -Q"?  If not,
some of your site-init files could be related to this.

It does happen with

   emacs -nw -Q -l /home/jrm/.emacs.d/custom-lite.el blah

as well.  One correction from my report above is that I said 'the
scratch buffer' above.  That's not correct.  Specifying some empty, or
non-existent file (blah above) is required.

Thanks, but I still cannot reproduce this strange problem on my
system, not with the current master branch anyway.

Does anyone else see this?

I cannot reproduce the problem either.  I used the macOS version, and
the way I compiled Emacs from sources is not exactly the same as in the
bug report, if that makes any difference.

I should have mentioned that the terminal was alacritty and it was
within a tmux session.  I just tried again with xterm and didn't see the
problem.  I just ended the tmux session in alacritty and started a new
one and no longer see the problem.

The problem _was_ reproducible, but unfortunately I have no idea what
circumstances caused it to be reproducible.  Given that restarting the
tmux session solved the problem, maybe we can close this and I can
re-open if necessary if I discover more information that pins the
problem to Emacs.

Thanks.
