I am painfully aware of this problem :-(
This is way my code which I posted to the linked article on
StackOverflow passes "-c /dev/null" to screen and also runs it in emacs

However, emacs is sufficiently heavy weight (socially) that you (as the
tramp maintainer) can ask the screen (and tmux and mosh) maintainers to
add the "-emacs" option which will disable all terminal drawing.
