Red flickering horizontal lines on screen

Hi there,

I was hoping somebody would be able to help me, I have a MacBook Pro 2020 13in (2GHz intel core i5, intel iris plus graphics 1536 MB) that while trying to play Netflix in full screen begins to present red flickering horizontal lines in the black areas. The redlines don’t appear when using the computer for anything else (YouTube etc). I’m not entirely sure what the problem is but I have updated it, turned it on/off, adjusted the brightness, moved the screen to see if it changes and nothing 😭

MacBook Pro 13″, macOS 11.6

Hi there,

You have a defective display and it needs to be replaced for that issue to go away. You can bring your MacBook Pro to Apple or an Apple Authorized Service Provider to be repaired.
