So, I was sky ping someone when I logged out and this appeared on my screen. It's not a crack, which is odd because of the angle the problem is at. At first, I was confused, so I gently touched it and the lines grew. The other side of the screen is perfectly fine, so I'm so confused on why this appeared. If someone could give me some help on a way to resolve this, that would be greatly appreciated, I need to write a paper for one of my classes! Thank you so so much!
