Flickering/glitching on the Screen
My MacBook Pro(version 10.15.7 from 2017) has black lines of flickering near the menu bar that will slowly drag/fill the top of my screen if I let it be. Therefore, when it gets bad or a lot of flickering, I will let it sit for a while and it will be gone. This has been going on for about three weeks, and it is getting worse. In the beginning, the flickering only happens after 3-4 hours, but now it happens even after 30 minutes or so of use. Is this a software or hardware problem? Screen problem? What can I do?
