Guessing no-one at Apple checked what happens when you have folder sharing on and Finder displays the opaque bar at the top... obviously looks even worse further right you go.
@curthard89 @Ragashingo If you do a screen capture of notification area or Control Center on macOS it’s been captured differently in each OS version so far. It’s my favorite broken piece. That and Mission Control flashing black when you have a full screen app that somehow is still not fixed four versions in. 
@curthard89 @Ragashingo The overarching feeling they did some partial architectural changes but didn’t complete them by release is hard to ignore. Like macOS is usable but there’s more fiddly bits than normal, though I’m very divorced from memories when they initially reset things after iOS 7 and how bad that may have been (forgot the macOS version for that)
