Hi there, I bought a 13" macbook pro 2017 with High Seirra 10.13.4 (17E199) for a week and I encounter a weird display issues when I watched videos on Netflix. The first time it was a screen blinking, it happened for a while then stop. After, sometimes the videos were moved a bit up and down. There also once, I saw a green screen glitch while I was watching a video. I've tried to re-installed OS and do what the Apple advisers told but it still happen from time to time. I'm worried whether it is just a bug or some hardware issues. Could anybody help?
