When I start tmux in my i3 / termite / zsh environment the default pane with the zsh prompt inside it is launched in a seperate window instead of the window in which I started tmux. Additionally I have some unicode characters at the top that can not be shown:
The statusbar of tmux remains in the window in which tmux was started.
If I close the derived window the original window outputs:
/usr/lib/xorg-server/Xorg.wrap: Only console users are allowed to run the X server
I know from other peoples setup that tmux should run in one terminal window as I know it from and it works in the same environment with screen, so what is not working here?
