Asahi Linux kernel 6.12.1-asahi-1 makes cosmic-comp use every available CPU cycle

Distro: NixOS 24.11
Kernel configuration:

  boot.kernelParams = [ "apple_dcp.unstable_edid=1" "apple_dcp.show_notch=1" ];
  boot.kernelPackages = lib.mkForce (pkgs.linuxPackagesFor ((pkgs.linuxKernel.manualConfig (rec {
    version = "6.12.1-asahi";
    modDirVersion = version;
    extraMeta.branch = "6.12";

    src = pkgs.fetchFromGitHub {
      owner = "AsahiLinux";
      repo = "linux";
      rev = "asahi-6.12.1-1";
      hash = "sha256-gXC+2I9N7Vg4aAfZYpFhCjZJWHrZpfSepuNDzIFHTuk=";
    };

    inherit (pkgs.linux-asahi.kernel) configfile kernelPatches config;
  })).overrideAttrs (f: p: {
    inherit (pkgs.linux-asahi.kernel) nativeBuildInputs buildInputs RUST_LIB_SRC;
  })));

When running the Asahi Linux 6.12 kernel and COSMIC, I've noticed the system feels extremely laggy and btop mentions the CPU usage is full on all 10 cores on my M1 Pro. It also shows cosmic-comp is using anywhere between 80% - 105% of the CPU. This feels like a strange regression to have from switching kernels.
