Screen Artifacts at Shut Down when using scaled display on 15" rMBP mid 2015 running Sierra 10.12.5 I am having an issue on a week old rMBP 15" mid-2015 running Sierra 10.12.5. I use the scaled display option and have noticed that there is a concerning screen artifact that occurs when I shut down the system. Other than that, it works perfectly. Does anyone have any idea how I should approach this? I have not reinstalled the macOS, but is that the only viable solution?

What shutdown looks like with normal scaling

What happens when I shut down with screen scaling
macOS has gotten a lot more quirky over the past few years. I've noticed many graphical glitches, myself. This is especially visible before the OS is fully loaded and also when it shuts down or sleep/wake events are in transition. 

I wouldn't worry about it, personally.
