> tmux/screen do not break copy-paste

Tmux breaks interacting with the clipboard so much that it has its own dedicated Wiki page dealing with all of the different issues and settings: https://github.com/tmux/tmux/wiki/Clipboard

[SeerLite]

It literally doesn't though. The wiki page is for copying tmux copy-mode's internal selection. The selection and copying mechanisms of the terminal emulator still work just as well.
