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?

I answered this last May in
Why does tmux fail to “scroll” when entering a command that exceeds one line? (OSX Terminal.app)
It is a known bug which does not appear with iTerm2.
