I've been using 1920x1080 144hz for months and everything was fine. This suddenly happened before I was going to do a factory reset. I thought it will be fixed, but I was wrong. Sometimes it's like this, or complete black over the same area.
Apparently I can "fix" it for a couple of minutes if I push it and rub my nails on it, so I know it's not a software issue. How do I fix this?
