I bought a 2020 MacBook Pro 13in in late june of last year. In october, I started noticing these weird lines on the screen when I was working. It was sudden (I blinked and they appeared). External monitor works fine. Any ideas?
Got a tip for us?

It's under warranty.
Take it to a brick-n-mortar Apple store and let them deal with it.

Any idea what might have caused it? Literally it was gone one second and appeared the next
Could be as simple as a video cable or complex as a display hardware issue. Get it in to a place where they can open it up and troubleshoot it.
did you run your macbook under stress and have heat built up? Many 2016-2018 Macbook Pros have the problem where the Display board with the t-con unit couldn’t withstand high heat and start to fail. My macbook included. I had to constantly keep my macbook cool to avoid horizontal lines.
