additional information:
mosh 1.3.0 on both
tmux 2.5
zsh 5.3.1
bad commit sindresorhus/pure:4cdd0cf, probably related to zle reset-prompt command. I didn't chase down what exactly this command does.

This doesn't look quite like screenshots at https://github.com/sindresorhus/pure. Are characters missing on the screen for you?

If so, that's a fairly good sign that you're having Unicode compatibility problems. Mosh relies on the system libc wcwidth() function to decide whether characters are wide or narrow, and most libc implementations lag far far behind Unicode releases. #234 has lots more discussion on this.

new lines exactly as displayed, i.e. mosh shows two blank lines before the tmux "footer"

seems to be fixed in master
