I am currently running tmux within Terminal.app on my Mac.
When I execute a command that outputs a line longer than the available window, instead of wrapping onto the next line, it overwrites the existing line.
What is also strange about this is: if I CMD+TAB to a different application and CMD+TAB back the output appears correctly on multiple lines.
How do I resolve this?
