I think the update did something with Nvidia drivers. I have a MSI 1070 with an Acer CZ340CK and I'm getting flickers of lines of artifacts towards the bottom of my screen. They're not all the time and seem random. I also blew everything inside me case to make sure there wasn't too much dust ( I do this once every 6 months anyhow). It only seemed to start after the Fall update though. I really hope it's not my card trying to go bad and it's coincidentally at the same time as the update to Fall Creator.
