I've purchased a new Radeon RX 470 (4 GB) card for my custom computer. I believe I have the latest drivers installed, however when used to play a game (Secondlife) with advanced lighting on, it never fails to produce an irritating glitchy line across the screen. Nothing I've tried to do has fixed it thus far, and I don't believe there are any other problems with the driver that I know of. I'm on the noob level of understanding technical terms for these kinds of things :/ So I've included a screen shot. I have noticed I was not the only one with an AMD graphics card that has had this problem.
