3639	Subshell output lost on window resize under tmux, GNU screen	yurikhan	andrew_b	"To reproduce:

1. Start xterm. Enable 256-color support:

    {{{
    (xterm)$ set TERM=xterm-256color
    }}}

2. Start tmux with the following configuration enabling 256-color support:

    {{{
    (xterm)$ cat tmux256.conf
    set -g default-terminal ""screen-256color""

    (xterm)$ tmux -f tmux256.conf
    }}}

3. Start mc:

    {{{
    (tmux)$ mc
    }}}

4. Hide panels by pressing `Ctrl+O`.

5. Generate some subshell output:

    {{{
    (mc)$ ls -al
    }}}

6. Resize the xterm window.

Expected behavior: shell output remains on screen (suitably padded or truncated to new window size).

Observed behavior: screen is cleared, with cursor remaining at the same position.
