How many weird terminal bugs do you have in your setup? Eg one that annoys me the most is that pressing esc in insert mode often takes a few seconds to do its thing.

any chance you have a key sequence mapping that starts with esc? sounds like its waiting to see if you are gonna be pressing another key before timing out and do its thing

It happens randomly, which makes me think it's a bug.

Unlikely. Start with empty configuration, and try to reproduce first.

It’s not a bug. The wait times is because the terminal supports escapes codes (which start with an escape character). So most TUI (which put the terminal into a special mode) have a wait time to distinguish between the two (because for the terminal there’s no difference between keyboard events and the software UI). I think it’s configurable in both tmux and vim.
