Hi, I am suffering from slight UI lag on a 2016 15". It's minimal, but still noticeable. Such as 0.5s lag and choppy transition into fullscreen mode. Closing windows, as well, is met with lag of about half a second. I know it's small, but definitely noticeable - and gets quite annoying. I don't see this is an issue to take it back to the Apple Store, but do you know any way to fix it? 15" with 460 Pro I've also had a poor experience with local Apple Store when having shutdown issues, and even though I was in return period, seemed angry when I asked to return it so I did it online. So, I'd rather not bring up such a minor issue like this, especially as I'm now out my return period. Thanks.
