Answer 1

Vim asks the terminal for its version, what you're seeing is the response (cp. :help v:termresponse). It only appears printed in the terminal; that's why you can't "edit" it and it appears after a redraw.

Why Vim doesn't properly receive it, I don't know. Switching the terminal program might help. You could also try to suppress the query via :set t_RV= in your ~/.vimrc.

Answer 2

I switched to neovim and I've never seen this issue anymore.
