Hmm. This sounds odd and interesting :-).
My instinct would be that it sounds unlikely to be a generic tmux problem but more likely either to do with the way tmux sets the terminal up, or in libevent, or the termios/tty layer. Although of course I could be wrong. Please don't be insulted if some of these questions you have already ruled out, these are just ideas: Does C-b r redraw the screen properly? What terminal emulator? I guess using a different TERM outside (vt220?) doesn't help? tmux HEAD? On Linux? What kernel version? There was a bug in one that tmux triggered, I forget which, I'll look it up. Might be worth attaching gdb to the tmux server during the pause and seeing what it is waiting in and what the state of the windows/terminals are. Can you try making libevent use poll rather than whichever wait API is fashionable these days on Linux? (EVENT_NOEPOLL probably?) Maybe try making server-window.c:server_window_backoff just return 0 and see if it helps. You could try fiddling/checking the flags in tty_start_tty. I've been running yes for ages with various output on OpenBSD with no ill-effects.
