Wow, why didn't I or any of the people below think of or try to fix it that way?! Because it doesn't work, smartass. Edit to add: there is no option to disable screenshots in Steam. You can change they key binding, which I have to no avail. I have even set the keybind to None, yet it continues taking screenshots. This has been going on for a years. The only thing that fixes it is disabking tge Steam overlay completely. https://steamcommunity.com/discussions/forum/1/3758852249521810319/ https://steamcommunity.com/discussions/forum/1/143388344303292710/ https://steamcommunity.com/discussions/forum/1/3557193237097355447/
