After upgrade to High Sierra, tmux + powerline refresh add extra ghost space characters.
- iTerm2 version: 3.1.5
- OS version: High Sierra 10.13.1
Since I upgraded to High Sierra, my terminal input gets extra ghost characters added when in tmux on powerline update.
Here is a video to show the problem: https://www.youtube.com/watch?v=JnYPt4PPkh0 (notice how the extra spaces get added when powerline's load average update)
Not visible on the video: if I backspace the whole line, the spaces get erased as 2 spaces, but I'm left with 2 'l' at the beginning of the line.
