My MacBook Pro (13.3 inch, MacOS Sierra 10.12.15,Late 2017) started to have grey horizontal lines appearing on my screen in Mid 2018. At first I thought it was not very serious and could deal with it, but later into 2019, a dark grey translucent stripe started appearing at the bottom of the screen. Still, I decided not to take action. It was when at the bottom of my screen started glitching and it started to take the graphics of a different app (swiping left/right with three fingers), but only at the bottom of my screen. The bottom started to have coloured glitches and little do you know, the top of my screen started to do the same. It was at the start of summer when it started to become worser than ever. Because the usage of my MacBook has increased far more hours than usual, the whole display started to fail. For example, if I was to be watching Netflix, the screen would freeze on one frame, but continuing what was supposed to have been playing underneath the first frame that was frozen. I could only see what was happening because it froze translucently, where I would immediately turn off my laptop to prevent further damage. Other example that may occur would be when I am on one tab (let's say, a Spotify playlist), and then swipe across my trackpad to a Google Document filled with writing, and then to my desktop. My screen would have my desktop wallpaper with a translucent overlay of both the playlist and the text that I would have been working on, on the document. I figured the fault may have been because of a crack at the bottom my screen, although I do not understand how that may have happened.
I will appreciate your help very much. Thank you.
