Blur under windows

[abakkk]

This issue is more about new extension idea than new feature.

Blur is a lack for Gtk, not only for Gnome-shell. Is it possible to localize blur under, and only under, opened windows ? In combination with transparent background in gtk windows (like gnome-terminal or with css theme for other applications), that would be an awesome trick.

When I open workspace overview while gnome-terminal is open and blyr extension enabled, I can see blur background under gnome-terminal windows thumbnail.

KDE just implemented this in Plasma 5.13. Might be worth seeing the way that they did it there. In addition to controlling blur you also can control the noise level which is nice.

It would also be nice if there were a setting to apply blur on window headers only
