Obtrusive selection box

I’m currently putting together some UI elements, but the selection box is getting in the way. I’ve looked through studio settings but I can’t find anything. Does anyone know how I can turn this off?
This is what I’m looking at, and it’s pretty obstructing.

I also have this problem as well, it’s very annoying!

This plugin should handle it for you, doesn’t seem to be a native studio feature though:
