Gamescope not working at all

[Anonyku05]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

Good evening,
I’m having a small issue with the application "gamescope," which is used to launch games/applications at a specific resolution. It used to work well, but after reinstalling Debian, I’m now getting this error message:

wlserver: [backend/headless/backend.c:82] Creating headless backend
MESA-INTEL: warning: Haswell Vulkan support is incomplete

I’m not sure what to do to fix this issue. Any help would be greatly appreciated!

PS: I'm forcing letterboxing because of a modpack in Minecraft that is meant to be played like that

I'm unfamiliar with Debian packaging. Is it up-to-date with the latest release of gamescope (3.15.14), or are you referring to the latest Debian 12 release? If the latter, what's the version reported by your package manager?

If Debian logs coredumps it would be helpful to see a coredump as well (coredumpctl, look for the number associated with Gamescope's core dump, and then coredumpctl info <x>) since there's not much to go on based on the log.
