Recently when I have been playing games, my screen has been glitching like in the movies were sometimes a chunk of a screen will jitter. that and every so often the monitor will turn off and on for a second. It's strange cause sometimes it will be completely fine for hours. Sometimes it will be terrible for hours. I also feel like it does it more when I'm not moving my mouse or typing, but I could be crazy. I have tried uninstalling GPU drivers with DDU and reinstalling both 'AMD's' stable and optional drivers (separately). I have tried remounting my GPU (RX 580). finally I have tried a new cable in both the same and different GPU sockets. nothing has worked. Please help.
