Strangely it seems to display on occasion. I have no idea what triggers it, but I just had one game session with the overlay work. Once I quit the game it broke again. It also does not work in the steam client itself even when enabled there. Nothing like inconsistent behavior....

I am having the same issue. I am on CachyOS, using the gamescope-session-cachyos package. Passing mangohud as an environment variable works, so I suppose it is a problem with mangoapp

I can confirm the same issue on Steam Deck LCD, OLED, and Steam Machine. All running Steam OS Preview and Steam Client Beta with SteamRT3 Steam Client enabled.
