About a week ago I noticed my MacBook Air's screen starting to have quick flashes of a vertical bar that would show up when ever I started to close the screen, but recently there was an incident where I opened the lid and left it, and then it started to continuously glitch out. I was wondering if there's any easy way to fix this without having to pay hundreds of dollars for a screen replacement. I attached a photo of what it looks like below. The screen still functioned and showed whatever I did on the screen but the bar remained there for a bit until it went away on its own. Thanks!
