How to disable animations for gtk-layer-shell -based app?

[iliabylich]

I have an app that uses gtk4-layer-shell, when it's active I don't see it in hyprctl clients:

$ hyprctl clients | grep -E 'class|title'
	class: code-url-handler
	title: hyprland.conf - dotfiles - Visual Studio Code

	class: google-chrome
	title: New Discussion · hyprwm/Hyprland - Google Chrome

	class: gnome-terminal-server
	title: ilya@debian: ~/experiments/dotfiles

Not sure if it's relevant but I can see it in hyprctl layers:

$ hyprctl layers
Monitor DP-1:
	Layer level 0 (background):
		Layer 557814341910: xywh: 0 0 1920 1080, namespace: wallpaper
	Layer level 1 (bottom):
	Layer level 2 (top):
		Layer 5578143638a0: xywh: 0 0 1920 56, namespace: bar-0
	Layer level 3 (overlay):
		Layer 55781448c070: xywh: 1420 56 500 205, namespace: gtk4-layer-shell

When I open it (obviously) I get a standard fade-in animation that I'd like to disable for this (and probably all other) gtk-layer-shell -based widgets. Is it possible to get it using windowrule{,v2}?

Why did you mark this issue as closed? I am facing the same issue, have you found a solution?

I did some reasearch and for anyone facing the same issue: you can use layerrules in the following way:
layerrule = noanim, gtk4-layer-shell

[iliabylich]

Yes, it's layerrule = noanim, <layername> where <layername> is whatever is the name of the GTK4 Window widget. You can always do hyprctl layers to see what's currently set.
