Original GitHub issue: https://github.com/games-on-whales/wolf/issues/306

All I see on launch, regardless of which of the two installation methods I choose, is a black screen in Moonlight. I couldn’t find any solutions in the issues, I don’t have the expertise to fix it myself, searches yielded nothing, and AI didn’t help in this situation either.
With the Arch + Wayland setup, the configs don’t work.
