First off, I’m on an xbox one X. (Not series x/s) Blurry in-game screen. But when things come closer to me they become more clear. Has happened to me 3 times. I restart the game and it’s back to normal. Happened on Mystery Heroes if I remember correctly.
I think it happens when I’m searching for a game, and I happen to open the social menu or any other menu at the same time as when a game is found.
