Comment:
I have a build of gamescope 3.12.0 in my [personal packages repo](https://github.com/Natthias/abyssal-packages), which also builds correctly, yet doesn't function properly.

It seems likely that the issue is this. Is this the same error message on your end?
`wlserver: [xwayland/server.c:270] Xwayland startup failed, not setting up xwm`

As an aside, you probably shouldn't package stb in this PR, as upstream doesn't provide releases. I think including it in the template for gamescope is the correct way to proceed
