I figured out why Gnome on Xorg was crashing. It was because of libinput-config. I noticed because it wouldn’t actually crash until the moment I moved the mouse. The game seems to work perfectly on Xorg.
I already tried gamescope. The results of that attempt are in my original post above.
Still, while I can finally play the game now, it’s a bit annoying having to remove a package and reboot everytime. I don’t even know if this is a Wayland issue or a Gnome issue but I don’t have the disk space to install KDE or anything.
Ideally I would like to figure out why this is happening in the first place and maybe report it upstream, but I have no clue how to even get debug logs out of this.
