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.

I have exactly the same problem!
I guess is not related to graphics cards as connecting to an external display shows no problem at all, but of course could be any other problem related to logic board like bad video connector and so on.

They changed only display or also logic board in your macbook?
