Every game, normally as a teamfight starts, my screen will go grey then come back after a few seconds as if it had just changed inputs. It sometimes affects my audio as sometimes I use speaker connected to monitor and other I use headset. I thought this would be my GPU drivers but after a fresh install using DDU it still happens. I have also tried repairing and reinstalling lol completely.
I don't get this problem with any other games and I normally play Destiny 2 and Apex Legends so it's not a matter of performance.
I've seen only 1 other person bring up [this issue](https://boards.na.leagueoflegends.com/en/c/bug-report/kFy3y9GR-grey-screen) and they got no fix.
