Valve just released the latest stable update to Proton, the compatibility layer for running Windows games on Linux desktop and Steam Deck with Proton 9.0-2 bringing some fun additions.
Dunno if it's every game, but it happened practically every time I would wake from sleep mode in Holo Cure. Didn't happen for the first time today, and the only new thing was the Deck downloaded the new Proton version right at game startup.
