Detailed steps to reproduce the problem:
- Open iterm
- Create a tmux session (run tmux)
- Using the mouse, select a bit of text on the terminal an copy it using CMD+C
What happened:
A banner appears on the top of iterm 
Notice that there is no option to prevent the banner from appearing again after it is dismissed.
What should have happened:
The banner should not have appeared, or it should have contained an option to prevent it from being shown again.
I have tried to locate any global iterm config option to disable this behaviour on the documentation and interface without luck.
