On Windows 11 when I press Ctrl + Shift + S, it nicely gives me a cursor to take a screenshot. Then if I do something else in game and then press that same key combo, the screen reverts back to the state of the previous screenshot I did. This behavior isn't present on my system for other apps (I just tried it on discord here and it works as expected, not reverting back to the previous state when I take a new screenshot).
