Sorry for the late response, I meant gamescope. I looked into it, it seems like umu-run has a bug where it expects DISPLAY=:0 but gamescope sets DISPLAY=:1. At least that’s my understanding. It has been patched in the repo but there’s no release with the patch yet.

Gamescope works fine if umu-run is not used to run the program.

I’m surprised to game can launch at all. For me it crashes instantly.

I was daily driving it but started crashing after an update. I’ll be getting back to it tho, I’m sure there has been like 4 updates in the last 24 hours…
