Black vertical lines covering part of screen and also lines going across bottom of MacBook Air2020
I opened my MacBook Air 2020 one day to a bunch of black and some other coloured vertical lines running across the right side of my screen.
There are also lines at the bottom of the screen, that flicker every time I use Google Chrome.
How do I fix this problem and is it serious?
MacBook Air 13″, macOS 13.4
