I had a long battle with making kitty work with tmux. I settled on the following in ~/.tmux.conf, before moving to wezterm for good. Maybe it fixes things for you, too: set -g default-terminal xterm-256color set-option -sa terminal-overrides ',xterm-kitty:RGB' set-option -ga terminal-overrides ",xterm*:Tc:smcup@:rmcup@" set-option -ga terminal-overrides ",screen*:Tc:smcup@:rmcup@" set-option -ga terminal-overrides ",tmux*:Tc:smcup@:rmcup@" I honestly don't know whether all are needed, or only some. But with these, it worked well for me.

I tried the first line and in some situations (specifically with some remotes, i.e. kitty -> ssh -> tmux with that 1st line) it still won't fix it. I gave up kitty because the author obviously don't like tmux and is advising users not to use it. So it is more like a choice between kitty and tmux. Giving up kitty is easier for me in terms of features and time for retraining. What's your reason to migrate from kitty to wezterm?

  > What's your reason to migrate from kitty to wezterm? My reason to no longer using kitty is simple: I don't like having to copy kitty's terminfo data to every single system I connect to in order to have my terminal work. It's fine for those few systems I very often connect to, of course. But I also connect to ephemeral systems, sometimes for a short session, and the toil and friction inherent in having to do that just isn't worth it. Sure, "kitty +kitten ssh ..." can work in most people's scenarios. Didn't quite work in mine, due to various intricacies about my ssh setup - multiple ssh keys, handled mostly by ssh-ident. wezterm Just Worked for me. As I got "back" to also using other systems like Windows and MacOS, it Just Worked there, too. No fiddling with terminfo, no fiddling with $TERM, either. Happy days.

    Your reasoning resonates with mine very much. I'll look at wezterm soon and hope it will works for me too.

You likely need all of them ;-) IIRC it "fixes" terminfo stuff "within tmux" for kitty regardless of what $TERM is set. Mind you, I was using the latest tmux at that time. tmux 3.2? Here's the issue I had: https://github.com/kovidgoyal/kitty/issues/3018 https://github.com/kovidgoyal/kitty/issues/3018 Looks like it should be fixed on a very recent tmux; otherwise this MIGHT help: set-option -as terminal-features ',xterm-kitty:RGB' ... or not.

    I tried your solution using one remote server that I had trouble with before and it works! That's really great. This probably solves enough problems with kitty for me that I can use it until I find a better solution. (I am using Alacritty at the moment but it has other problems so that I have to use kitty as fall back for some situations.) Thanks!
