So I've lived with this problem for several weeks now, hoping that if I just let it happen enough, I would figure out the underlying trigger. No luck.
tmux in bash in gnome-terminal in XMonad on Ubuntu 14.04.1 LTS (clean install). same bug in when instead of XMonad I use vanilla Unity (even clean installed).
It seems that every now and then something is printing the character u'0x001b', superimposed over a ']' character in the string "]112" instead of recognizing this as escape followed by some numbers, tmux prints it verbatim to a (random) position on the screen.
Recently, the string "]112" has also started to appear without the unicode character very occasionally. It appears that if the characters go off the end of a vim line, replacing the first one can sometimes leave the others intact.
Anything that forces a redraw of the rectangle holding the unicode character gets rid of the whole sequence of them. In Vim, I can delete each individual character in the string "]112" as if it was actually there, however. Simply changinging their colors, e.g. by positioning the cursor over them in vim, does not get rid of them.
I don't have enough reputation to post images, but I'll host a little screencast of what the problem looks like at: http://www.brunobeltran.com/junkdump/tmux_error.mkv
Below is my .tmux.conf. I have played with various values for the escape-time, to no avail. Also, removing mouse stuff does not help.
Any idea or things to try would be greatly appreciated!
