blur partial window

[rinmyo]

Is it possible to blur some specific parts only of a window. like 'title bar', ' places area of nautilus', or more particular condition like "all areas whose opacity less than 1"

It's a little hard to implement. the blur effect is just add a blur layer behind window, and simply change the opacity of window.A feasible way is to change opacity of title bar by editing css of gtk theme by yourself, and add window to blur list.

Try to look for GTK themes that provide transparent components. For example WhiteSur has transparent favorite bar for nautilus, you can use the theme and set opacity to blurred windows to 1 so titlebar and other components won't be transparent

Like alpha blurring in compiz, that would do the trick. Though it can be chaotic with fading animations etc, that's why KWin for instance uses a blur atom on surfaces that want to be blurred
