So if I play any YouTube video, I get some strange lines on the screen. I know it's not a faulty monitor, because with my TV the same happens and it also shows the lines on a screenshot. Here's the screenshot:
There are blue/green lines all around the character's head, but it's most noticible on his nose. I've never had this issue before, it's happening since today. I'm running Chrome 76.0.3809.100 (64-bit) on Windows 10 Pro. I first thought it was an issue with the insider preview I was running. but installing the stable 1903 didn't change anything.
