Describe your issue/feature…

Around specific popups and context menus in hyprland, I get borders that are a blurred version of the background that would have been behind them.

Is there something I can do about this, and/or what could be the cause of this?

Thank you!

Yes. This happens when you have blur enabled and an XWayland window opens a popup with client-side decorations.

Hyprland cannot know what is the window and what is the decoration (we get one buffer), so we blur it all.

Simplest solution is to not use your (browser, I presume) in xwayland.

More complicated one (and less recommended) is to set a noblur windowrule for it.

In general, I always recommend to avoid xwayland as much as possible.

Thanks a lot for the quick reply! I am actually not concerned with chromium, as I don’t use it; I just wanted to give an example.

I have an issue with the blur around ULauncher, as that is my favorite app launcher, and as you can see, it has transparency and background blur, which I would like to keep, so I assume noblur is not an option for that.

If I understood correctly, xwayland just supplies the area of the window, and you put a blurred version of the wallpaper behind the window there? That would make it very hard to both keep the blur and remove the blur around it…

Simplest solution is to not use your (browser, I presume) in xwayland.

Does this mean I should just not use the app (in this case, ULauncher, not Chromium) on hyprland, or did I miss something, and I can let it run in native Wayland?

IIRC ulauncher is not a proper wayland launcher. It uses hacks to be a “launcher”. It doesn’t support wayland properly, that’s why this happens.

Welp, that is unfortunate. I guess I will live with it (I mean it also has an aesthetic) because I don’t see any other launcher that I like as much as this one. If you have recommendations, feel free, but no need.

Thank you for your fast replies!

I like walker :) GitHub - abenz1267/walker: Multi-Purpose Launcher with a lot of features. Highly Customizable and fast.

Thank you. I will stick to ULauncher, because I like configuring it with Python. There is no need for you to reply here anymore.
