I have had my HP Spectre x360 for a couple years now, and for a long time there has been this thing in the top left of my screen. It does not impede regular use, and you can't even see it from some angles. It's just one of those things that annoys you just from the knowledge of it being there. My current theory is that it's some kind of rubber sealing that's just sagging down and covering the screen a little bit. I have a 4K touchscreen, so I'm not exactly comfortable messing around with it or taking it out myself. Tapping the edges of the screen has minimal/no effect. I would also rather not hand it in to Best Buy or something shady like that. Does anybody know what it is or have a solution? https/imgur.com/a/Lfauc8u
