an-anime-game-launcher (genshinimpact.exe) renders at 2 fps

[whymusticode]

the launcher is fine, it's the game that got borked.

v52 regression, worked in v51. I've been using ignorepkg since the change, but figured I'd mention this here in case anyone else wanted this fixed

problem goes away changing resolution in game, but it takes forever to do that because its rendering at 2 fps
renderunfocussed doesn't fix it, nor does any windowrule. all other games uneffected. this is a wine game with dwindling maintainence, so possible if wine updates are necessary, this game is not getting them. flatpak and AUR version both have same behavior. There's a setting to use gamescope, fixes the problem, but it crashes as the game loads in

======Config-Start======

[Anreol]

Having the same issue with Blue Archive, seems like it's a regression since v0.52.0, as I've tried both V0.52.1 and V0.52.0. Works fine in V0.51.1

The issue itself is the same: the game locks itself to 2fps shortly after the splash screen, which I personally believe its the game reducing resources to a minimum as if it were "tabbed out", as this same behavior happened before if the game was in a different, non active workspace, but this is just me going off my guts.
Both Genshin Impact and Blue Archive are Unity games, though not all Unity games are affected by this, for example, Limbus Company works fine. Limbus Company does not have the "reduces fps when in a different workspace" behaviour I've described, neither before nor now.

The game itself does not need to specify compatibility tools, but I've tried multiple different Proton versions and there's no variance.

Building by adding hyprland as a flake input, specifying the release tag and also using cachix:

nixConfig = {
    extra-substituters = [
      "https://hyprland.cachix.org"
    ];
    extra-trusted-public-keys = [
      "hyprland.cachix.org-1:a7pgxzMz7+chwVL3/pzj6jIBMioiJM7ypFP8PwtkuGc="
    ];
  };
  
 inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    hyprland = {
      url = "github:hyprwm/Hyprland/v0.52.0";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    (...)
}

For more information, I initially asked in the Steam Discussion Forums, where someone replied that they were still using v0.51.1 without issue which gave me the idea to downgrade, and someone else on 0.52.1 having the same problem as I do but slightly different, I add here:

I sometimes get that problem (0.52.1). For me, it has something to with the game resolution, as it usually happens whenever I try to manually resize/move the window. Try messing with the in-game resolution setting and see if switching to windowed/fullscreen fixes anything.

[whymusticode]

it's the same render as if it is unfocussed, likely related to this:
fix render_unfocused

[vaxerski]

first, please check if it goes away when you disable direct_scanout (if you enabled it)
second, please bisect: https://wiki.hypr.land/Crashes-and-Bugs/#bisecting-an-issue

[Anreol]

Spent some time bisecting, using a nix develop shell to make, and using Blue Archive as that's what is affecting me, got as a result the following commit:

➜ git bisect bad                  …/Hyprland on  HEAD (8e8bfbb) (BISECTING) via △ v4.1.2  4m30s627ms 
8e8bfbb0b146fb1f3234b2a3e3e92b63989e1993 is the first bad commit
commit 8e8bfbb0b146fb1f3234b2a3e3e92b63989e1993 (HEAD)

Additionally, I did not have direct_scanout enabled.

[gulafaran]

does this change anything? with this it should be somewhat same as before that commit with fifo still working.

hm.patch

[Anreol]

It fixes it.
For more proof, the following two attachments are: first that commit without the patch and then the same commit with the patch. Note the upper left corner for Steam's FPS counter and FPS graph history, and in Kitty the dirty and clean status for the branch status.

The small white window below the FPS counter is Nexon's Anticheat which launches alongside the game.

Note aside, I'm unsure if I kinda hijacked this discussion with my own issue, as the way I described it is slightly different to OP's, which is closer to the description I posted from a third user on the Steam Discussion Forum, and it's also a different game, but I thought it was close enough to mine to post in it instead of creating a new one (I have done a search for similar discussions and all that jazz), so forgive me if it wasn't right.

[gulafaran]

since i cant reproduce locally but seems to point to the fifo commit, see if #12461 solves it.
