Original GitHub issue: https://github.com/games-on-whales/wolf/issues/520

Apparently MANGOHUD=1 in the image causes mangohud to be loaded on steamwebhelper in Big Picture, that makes Steam act weird as it no longer tries to detect processes when you launch a game, and the overlay doesn't work (I can't take screenshots, for example), this is especially evident after a re-launch (stopping and starting Steam through Wolf UI).
I disabled the env var and used SteamClientLaunch=1 as part of the MangoHud layer config and that seems to work reliably so far, but this is a workaround and I have no idea what I'm doing.

EDIT: it happened again, so my initial report was inaccurate at best. Still something worth investigating, I'm happy to help debug. TL;DR: Steam overlay doesn't work on the Steam image, especially after a container relaunch.
