My screen just randomly gets these weird line. It's only my primary screen and the first time every restart it appears, if I shut my screen off and on again, id goes away for about 1-2 min, after which the screen restart isn't effective. It happens roughly 3-4 hours (maybe more) after start up, and it's happened 3 times so far. Rebooting solves the issue, at least temporarily. Weirdly, it only happens on one screen, and when I take the VGA cable out of my GPU, the lines move to the other screen (which then becomes the primary one). The color depends on the background I had on.
