Nope, it's probably something different, reloading did not fix it for me. The baffling part is it started suddenly without warning about 1 year ago. For Skaz it started now. It was happening only when CP was active. I suspect the new drivers of the graphic card were downloaded and changed some settings without permission.
Ya, I said that reloading didn't fix it. Restarting did, however. Happened to me twice now. I tend to leave the game open for long periods of time, >24 hrs.
