iTerm2 outputs random characters when the remote tmux exits abnormally

Question

I use tmux on my remote terminal. I found that when the remote terminal was disconnected abnormally (e.g., I just closed my laptop without exiting remote terminal normally), my terminal on iTerm will start to output random characters if I scroll my mouse, or click.

Any advice how to fix it?

Answer 1

I had the same issue and found this answer which helped me: Disable mouse reporting in a terminal session after tmux exits unexpectedly

To disable Mouse Reporting from bash, use this code:

printf '\e[?1000l'

Answer 2

@cory's solution to reset the mouse reporting is effective. To automate this process, I'm using the following bash function:

function ssht() {
    ssh -t "$@" 'tmux'
    printf '\e[?1000l'  # to avoid mouse reporting issues
}
