I’ve installed mosh to see what it actually is. The man page speaks about speculative local echo which sounds like asking for trouble... Anyway, I could reproduce effects as you described with mintty – tmux – mosh localhost (no additional screen needed) And, most interesting for me: the same thing happens in xterm, so it’s not a mintty issue :) > Actually I have found a bug in the combination of auto wraparound mode > with scrolling region margins and origin mode. > Once fixed, that could even affect the issue, we'll see. The supposed bug mentioned before wasn’t related to scrolling regions. Instead, I’ve tried to mimick xterm in some obscure border cases, and now the vttest case 1 page 3 passes as well. ------ Thomas -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
