No Game appears to work anymore when using Gamescope

[CaptainCoward]

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

I had several games using Gamescope. I didn't touch anything on their launchparameters but something seems to have broken gamescope. No Game will start anymore, even if i just add gamescope without any launch commands. I tried different combinations like adding --backend sdl or --backend auto though nothing seems to help

Edit
I just noticed that this is caused by a System Update. I had Gamescope (3.15.14-1) working on my other system that wasn't yet updated. I updated it and now i run in the same Issue there as well.

Steps To Reproduce

Launch any Steam Game using any Launch Parameters, i recommend Aero GPX Demo since it is free. (Game i have tested Titanfall 2, Rainbow Six 3, Quake 2, Amid Evil, Redout 2, Aero GPX Demo)

An example of launch parameters that worked fine for me but just stopped working would be:
gamescope -W 2560 -H 1440 --force-grab-cursor %command%

Hardware information

- Distro: EndeavourOS
- CPU: 5700X3D
- GPU: RX7700XT
- Driver Version: Mesa 1:24.2.6-1

Software information

- Desktop environment: KDE Plasma
- Session type: X11
- Gamescope version: 3.15.14-1
- Gamescope launch command(s): doesn't seem to matter i used gamescope  -W 2560 -H 1440 %command% most of time

Which gamescope backends have the issue you are reporting?

• Wayland (default for nested gamescope)
• DRM (default for embedded gamescope, i.e. gamescope-session)
• SDL
• OpenVR

Hello @CaptainCoward, as a quick test, can you add -- just before %command%? (e.g. gamescope -W 2560 -H 1440 --force-grab-cursor -- %command%)

[CaptainCoward]

Omg thank you, that seems to be it. At least the game starts now! Should i close the Issue?
