Answer 1

Had a similar issue, where I had a tmux session with two buffers. I didn't see anything I typed, but when I switched between buffers what I had typed previously would appear onscreen. stty sane didn't work.

I detached Ctrl-b+d, and noticed that there was still a client attached when I looked at tmux list-clients. tmux detach-client removed it, and then I could reattach and the everything worked again.

tmux was halting right after I started it. Ctrl-Q and Ctrl-C didn't do anything.

Fixed with
