Can you blur specific elements of a LayerSurface?

[colin-heffernan]

I'm using EWW and I want to be able to blur certain widgets, but not others. Is this possible? I asked this in EWW's repo and they said that blurring was the compositor's job.

Probably not, since eww uses gtk-layer-shell, which is one surface to hyprland, so there's no way to tell hyprland where to blur.

I think it's possible, if you have multiple defwindows.

› hyprctl layers
Monitor eDP-1:
	Layer level 0:
		Layer 1dd0bd0: xywh: 0 0 1598 999, namespace: wallpaper
	Layer level 1:
	Layer level 2:
		Layer 1db2d50: xywh: 0 0 1598 32, namespace: gtk-layer-shell
		Layer 1450830: xywh: 1597 42 1 946, namespace: gtk-layer-shell
	Layer level 3:

This is how it looks on my setup. 1db2d50 is my bar and 1450830 is my notification panel.

You can blur surfaces using blurls: https://wiki.hyprland.org/Configuring/Keywords/#blurring-layersurfaces.

Ah yeah. You're right. My mind was elsewhere.

Then I guess no, you can't do that unless eww can display different namespaces to different widgets (if at all possible).

[colin-heffernan]

For context on why I need to be able to open and close the widgets: I'm trying to make a start menu with a blurred background. The issue is that the widgets have rounded corners, and the parts where the corners are transparent are blurred.

[colin-heffernan]

Alright, then I guess I'll go without blur. Thanks for the help.

[fufexan]

Yeah, hyprland can't really know how to cut the blur on corners, since all layersurfaces report is a rectangle.

I opened an issue in EWW as a feature suggestion allowing for different namespaces on different defwindows. Hopefully it's possible to implement.
