When in Menu, Disable View of Game?

I am using Lakka 2.2. When I press L3 and R3 to access the menu while I’m in a game, the menu appears. But there’s also kind of an opaque screen freeze that the menu gets put on top of. In previous versions of Lakka, it was just the menu, no screenshot. I’d like to remove the view of the in-game screen and just see the menu. I’ve messed around with settings like opacity and disabling the “overlay,” restarting between adjustments. But nothing seems to make the screenshot go away when I’m in the menu. Does anyone know how I can make the screenshot go away while I’m in a menu? Lakka 2.2 build for PC.
