When the "pop out sub menu " the pop out has its own black back panel , but the whole screen goes black behind it , is it possible to have the screen( full screen)  still showing , maybe blurred rather than a full black screen when the submenu pop up appears ?

It shouldn't be black - it should only be dimmed slightly. Looks like somewhere in the recent changes, the dim was getting applied twice making it look really dark. Should be fixed now so it is only slightly dimmed.

Unfortunately blur overlays are not possible -- I can only blur a specific image, not actual parts of the screen.
