Describe the question

Is it impossible to show image previews kitty + tmux?

I already did how to configure yazi inside tmux from the docs. I built tmux with sixel support. Still can't manage it to work.

Anything else?

No response

for someone having this issue in the future, make the TERM value equals xterm-kitty. also make sure your shell configs (.bashrc, .zshrc, etc.) don't override this env variable.
