Bug

Description

I have enabled blurring on waybar, tested with both blurls and layerrule. I am using hyprpaper to change wallpapers when I change workspace. When I navigate between two workspaces that each have windows, the wallpaper is correctly updated behind waybar -- when I naviagte to a workspace that has no windows the wallpaper is not updated behind waybar. If I open a window in the empty space the background behind waybar corrects itself

How to reproduce

• preload multiple images in hyprpaper
• add layerrule/blurls for waybar
• bind workspace navigation to change wallpaper with hyprctl hyprpaper wallpaper "" as per documentation
• Use bind to switch between workspaces that have windows and no windows open

Could this be related? I can't easily reproduce as it's random. It seems if I move the window e.g. Press meta and move with mouse it will go away, but then come back as it goes back to the same size as it was before I pressed those keys and moved it. Also, when my wallpaper changed it went away, I am using wpaperd with a slideshow for reference

I imagine something is getting out of sync perhaps and this is some kind of optimization? I was running Mistral AI 7bx8 on CPU which of course puts a lot of load on my CPU

[vaxerski]

it is an optimization. Why not try the patch?

[nonetrix]

I might look into that later not sure how to apply it on NixOS but probably isn't too hard? Hopefully? Will it be upstreamed eventually?

@nonetrix you can use this override:

wayland.windowManager.hyprland.package = pkgs.hyprland.overrideAttrs (old: {
  patches = (old.patches or []) ++ [
    (pkgs.fetchpatch {
      url = "https://github.com/hyprwm/Hyprland/files/13835169/patch.txt";
      hash = "";
    })
  ];
});

Change as appropriate for either the NixOS module/flake package.

The first time it will fail due to mismatched hashes. Copy the "got" hash that nix provides, and set the hash to that.

I just have a shell alias to get the hash from a URL, just a nice tip. I'll look into that tomorrow though

I fixed this issue by putting this layerrule in my hyprland.conf:

layerrule = xray,waybar

Makes sense considering Waybar needs to be able to update itself on background change.

[vaxerski]

can you test today's git

I've been looking for this solution for a long time, thanks TT

This has been fixed for me
