Try

  emacs -Q
  M-x shell
  $ ksh
  C-x 2

On my Debian desktop (running Buster), that's enough to provoke
misbehavior, without even resizing.  Resizing just makes the issue more
apparent. :-) This is with Emacs 27.2 and Emacs 28 (15c57fc4cc); the
build information for Emacs 28 is below.  (The git changeset doesn't
match what I just wrote because my build includes a couple MH-E fixes
that I need to get reviewed before pushing to savannah.)

I also see the problem on a Debian Bullseye test system, using the
bundled Emacs 27.1 (emacs-lucid build).

cheers,
mike
