If using Terminator make sure to set the TERM variable to "xterm-256color" currently I have only found a workaround for this by using a custom launch command:
TERM=xterm-256color bash
| # Append this to screenrc | |
| termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm' | |
| term screen-256color | |
| # Optionally: use current bg color for erased chars | |
| # defbce on |
| # Append this to tmux.conf | |
| set -g default-terminal "screen-256color" |
