It started this morning. Goes away for a few minutes and comes back. Especially upon opening and closing the lid. Can't be captured via screen shot, so had to video it with my phone. I have a 2017 MacBook 12 inch. Set up a mail-in repair so it should be fixed soon. I have AppleCare+ so hopefully this issue is covered. Any ideas what went wrong? Thanks for any help :)

hardware failure. Many old macbook pros had this issue with the discrete graphics chips, though your device shouldn’t have a discrete graphics chip so it’s probably more likely some other mainboard problem.

Make sure you back up all your data, in case they have to replace the main board.

I wonder if this could be a problem with the display cable/ribbon that attaches the display to the main board.

Thanks :) Before I mailed it off, I noticed that the flickering lines stopped when I would adjust the lid to a certain angle. Made me think it may be some sort of issue cable running to the display via the hinges.

Thanks for your reply :) I definitely made sure to back it up. It was super difficult with one USB-C port though, lol.
