Disable re-allocate size animation under hyprland

[thomas-btst]

Hello,

I’m using Aylurs Gtk Shell (AGS) under Hyprland and created a notification widget. When multiple notifications appear, each new notification triggers an animation due to the window being resized. I understand this is a Hyprland behavior, but I’d like to disable it.

I read that it can be disabled using the wmclass in a Hyprland config like:

windowrulev2 = noanim, class:^(ags)$

However, I haven’t been able to find the correct wmclass for AGS.

Do you know how I can find it? Or is there another way to prevent this animation?

I can also share my code if that helps.

Thank you!

<window
        class="notifications"
        visible={notifications((ns) => ns.length > 0)}
        anchor={Astal.WindowAnchor.TOP}
        layer={Astal.Layer.OVERLAY}
        exclusivity={fullscreen((fullscreen) => (fullscreen ? Astal.Exclusivity.IGNORE : Astal.Exclusivity.NORMAL))}
        marginTop={fullscreen((fullscreen) => (fullscreen ? Env.margin : Env.margin / 2))}
>
        <box orientation={Gtk.Orientation.VERTICAL} spacing={7}>
                <For each={notifications}>{(notification) => <Notification notification={notification} />}</For>
        </box>
</window>

The namespace of windows by default is gtk-layer-shell or gtk4-layer-shell depending on version. You can set Astal.Window.namespace to change it.

<window
  namespace="my-window"
>
</window>

You can also find out existing layer names on Hyprland using hyprctl.
