In this picture below you can see the Apps backgrounds are translucent can we get similar feature on Solus (Budgie ) too?
Specially on apps like nemo, Firefox, Brave

You can make them transparent with a little .css coding, other than that blurs for Plasma and Gnome.

    GTK themes are written in CSS (or SCSS, or SASS, and compiled to CSS). QT/Plasma has an entirely different method of theming.

    As for actual blur, I don't know how to accomplish this on GTK; I didn't think Mutter supported it at all.

    Only if you want to edit the GTK themes you're using to have transparency 🙂

    In Plasma blur is default but if you want your windows to be blur you need to install kvantum and a kvantum theme from kde-look.org. Usually when you pick a theme the creator has link to their kvantum theme that match.

    In Gnome you need "Blur my shells" extension to get blur effect.

        SethStorm666 In lxde and xfce and solus bspwm (hopping) I've been able to achieve this effect with Picom, which is not a difficult.conf to edit. (I know xfce has it's own compositor).

        it's got to be possible in Budgie (?) but I've never seen a single forum post about it.

            SethStorm666 it's a compositor people use in WM's and DE's for window opacity and blur, among other things, and treatment of individual apps. you have that pinpoint control like you get editing CSS except it does it all thru .conf. best way I know to describe it.
