I have the same issue on an Debian 5.0 vserver installation, Im using tmux only over an SSH connection.
The screen wont be refreshed, eg if I type something I dont see the result, till switch the tab and then switch back... The bug only appears from time to time, also when I dont restart tmux the buggy behaviour dissappears for some time... Thought first its because I had used the libc6 stable version instead of the testing ver, but upgrading to libc6 testing dont solve the problem.. Dont know the steps to reproduce it, maybe SSH connection losses have something todo with.. ii libc6 2.10.2-6 Embedded GNU C Library: Shared libraries ii tmux 1.2-4 terminal multiplexer i libncurses5 5.7+20100313-2 shared libraries for terminal handling i libevent-1.4-2 1.4.13-stable-1 An asynchronous event notification library ii libevent1 1.3e-3 An asynchronous event notification library best regards Fabian
