Mangohud randomly stopped working with Steam Flatpak

Not sure what happened but I've been running Steam games using MANGOHUD=1 gamemoderun %command% and it's been working fine with Mangohud. Suddenly, no Mangohud. Mangohud still works with Lutris.

I am using the Flatpak version so I looked at my history and there haven't been any updates to the Steam or Mangohud Flatpaks when the breakage occurred. Nothing relevant is logged out if I run Steam using flatpak run com.valvesoftware.Steam. Inside Steam there have been a few updates, including an update to the common redistributable and that may have been around the time this broke. The only other thing I see is that Gnome updated some Flatpak stuff recently as well.

System wise I am on OpenSuse Tumbleweed using KDE Plasma 6. Any tips for debugging further?

Relevant Flatpak packages

same experience, thank you for asking

I could not understand if I messed something up myself or not

See this issue: https://github.com/flathub/com.valvesoftware.Steam/issues/1280

There are at least two workarounds in the comments.

Thanks.

Ended up adding :/usr/lib/pressure-vessel/overrides/share to the end of the XDG_DATA_DIRS environment variable as described in https://github.com/flathub/com.valvesoftware.Steam/pull/1281/files.

Pretty non-intrusive workaround I ended up using as well.

A fix has already been published to Steam stable on Flathub. Workarounds can be removed now.
