When i try to open my MacBook Air, sometimes the screen looks glitched, this happen twice the last week, and i didn’t took a picture, but the last time i did. I think this could happen because i deleted all my files and restore mac a couple weeks ago. Is this problem gonna cause more damage to my device? Is this covered by the warranty or i’m screwed :(

You have a hardware level issue, a messed up OS install would be more consistent. Time to visit an Apple Store or authorized Apple service center.
