In Xcode 7.3, the visual debugger no longer shows a light gray outline around each view, making it difficult to view different views. This is what I see (this is missing a gray outline):

This is what he used to display in Xcode 7.2 (it has a gray outline around the views): 
Any ideas why, something I need to get back, maybe a mistake? I tried to switch the options at the bottom of the visual debugger.
I'm showing Wireframes and Contents , and the switching restrictions seem to be broken too!
Does anyone else see this?
