@Ethsan Can I patch ranger on my own using this PR? Would things work as expected? Can't wait for this PR to go into the next release.

Feel free, remember to allow passthrough in tmux and it should work like a charm. I only tested it on my machine, if there is a problem don't hesitate to tell me.

This issue was happening to me as well, even though I don't use tmux. While using kitty to preview images, ranger would freeze after opening any image file. This PR fixed it for me. Thank you.

For anyone wanting to patch this on nix, you need to add a couple of extra deps. As an overlay:

(self: super: {
  # Use ranger PR, fixes freeze after opening image in kitty: https://github.com/ranger/ranger/pull/2856
  ranger = super.ranger.overrideAttrs (old: {
    version = "1.9.3";
    src = super.fetchFromGitHub {
      owner = "Ethsan";
      repo = "ranger";
      rev = "71a06f28551611d192d3e644d95ad04023e10801";
      sha256 = "sha256-Yjdn1oE5VtJMGnmQ2VC764UXKm1PrkIPXXQ8MzQ8u1U=";
    };
    propagatedBuildInputs = old.propagatedBuildInputs ++ (with super.python3Packages; [ astroid pylint ]);
  });
})

@thenbe I think I see why it work but I am not sure. Do you use a terminal multiplexer ? What is your TERM variable ?

Whatever is set by kitty by default, I haven't changed it.

$ echo $TERM
xterm-kitty

Lmao I don’t know why it work but good for you.

@Ethsan I think I was affected by this bug: #1603 (comment). Originally, I was on latest stable release. I only got the fix for my freezing issue when I patched ranger to point to your PR, since the fix for my issue has only been merged to master but not released yet. Still, thank you for contributing.

Not sure if this is the appropriate thread but hopefully it's still useful to some.

I've been waiting for tmux+kitty+ranger+wayland support for a long time. Then I just realized ueberzugpp supports tmux on sway. It just works out of the box: https://github.com/ranger/ranger/wiki/Image-Previews#with-ueberzug
