Since one of the last updates, the behaviour of my Picture Elements Card has changed:
I use a picture of my floorplan to switch lights and various other things.
When I now click on an “action area” (e.g. my living room) it not only toggles the lights, but also overlays that “action area” with an eliptical “shaded” area (i.e. slightly darker than before).
When I click into another room, the living room is OK again, but now that eliptical shape appears in the new room.
I’ve noticed the same, there is a grey circle around my picture element icons when I click on it. It stays there until you click somewhere else (or another window). Not sure of the benefit, I guess it shows the last place you clicked ?
