I'm saying that some parts of the display are scaled by "C-x -" while
others aren't, and that is what causes misalignment.

list-processes is not a good example: it depends on what is going on
in the session, and in "emacs -Q" the display will generally be
empty.  Can you please use some other command, and explain there what
is wrong with scaling the display?  Because I don't think I understand
the descriptions so far, and the movie that was posted by the OP I
cannot watch here.

Thanks.
