Thanks for your response.

> How tall is your tmux pane? If it's very small it might still flicker as CC tries to redraw scrollback. I've noticed several tmux users have layouts where they stack several panes on top of each other making each one quite short.

It's full screen ("maximized" as tmux calls it).

I'll give it a shot.
