Describe the bug

After updating my system, launching kitty results in:
[1] 4976 segmentation fault (core dumped) kitty
Updated to kitty 0.34.0 #304261

Also mentioned in PR above:

This seems to be segfaulting on Hyprland for me. I don't know if I should open a bug report for this or not.

I'm unable to reproduce this on Hyprland 0.39.1 @ 79a139c9495568f69dd995bce1ca579247a98a17 and on Kitty 0.34.0

Are you able to run strace kitty and post it's output?

It's a bit long so here's a sharetext (exceed pastebin limits): https://sharetext.me/6tns9l93pv

[meirisoda]

hyprctl version gives me v0.38.1 - I'm using hyprland using wayland.windowManager.hyprland.enable on home-manager.

hyprctl version gives me v0.38.1 - I'm using hyprland using wayland.windowManager.hyprland.enable on home-manager.

Can you try with the latest flake?
I can't reproduce with 39.1.

The above screenshot is of kitty itself.

Can you also try this: #304725

I'm having a difficult time getting the flake to work using this - my Hyprland config is in home-manager, and following the instructions on the link above returns error: The option wayland' does not exist. Definition values:`, referencing the Hyprland flake.nix. It seems there was another person with this issue but can't seem to find a way to resolve it smoothly.

[JohnRTitor]

You can use wayland.windowManager.hyprland.package to ask Home Manager to use Hyprland package from the official flake.

First define it in your flake.nix. Then use it like this. (I don't use Home manager to install Hyprland though)

[meirisoda]

It's not exactly working, I've tried many different ways (enabling and defining it with just programs.hyprland and disabling home-manager's enable; using both; using just home manager and defining the package etc), but it always reverts back to a default config. There was one time it also mentioned segfault on the bottom text. I was also unable to verify the version.
kitty did not open on any of these times.
It is imported properly into my flake and hyprland.nix file (which includes my home-manager options that I use to configure hyprland).

[Kyesarri]

I've found using home-manager with

home-manager.users.user.wayland.windowManager.hyprland = {
          extraConfig = ''
          source = /foo/bar.conf
          '';
          };

allows me to have a custom config file elsewhere (in my nix git).

I had the same issue, with kitty 0.34.4 and hyperland from commit 82222342f10a7eff0ec9be972153e740d0f95213.

For me, removing background_blur 1 from my kitty config fixed the issue.
Maybe it's connected to having 2 different blurs (from kitty and hyprland) enabled at the same time.

[meirisoda]

This solved the issue! I had noise on in my hyprland config.

[YaroKasear]

Removing background_blur did not work for me.
