- static ones
- elements that spawn dynamically
- elements in far corners of the map
- showing and hiding it

Shows up here:

And moves accordingly. One note, widgets that are hidden and / or not in the viewport do not Tick. Not sure if relevant here, though. But I’d recommend against widgets pulling data.
My suggestion is to look at the actual numbers your setup is producing.
