Image is not displayed with tmux 3.3a or higher

[gnvk]

Not sure how to debug this :( Instead of the image, imgcat displays only empty lines.

macOS version: 13.1 (22C65)
iTerm2 version: 3.4.19
tmux version: 3.3a
python version: 3.10.3

What data are you trying to display?

It doesn't matter, the same happens with any image. For example with the wikipedia penguin.

I have also encountered a similar problem, but in wezterm.

Can reproduce this. It worked before, so I guess TMUX has changed some protocol. Will fix soon.

tmux 3.3 has broken passthrough of escape sequence. You'll need to have the following lines in your ~/.tmux.conf for tmux 3.3 or higher:

set-option -g allow-passthrough on

Thank you @wookayin!
