All the Proton games crash, normal Linux apps work fine

[vproper]

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

After launching any Proton game on Steam, the gmae immediately crashes before Proton even launches

Steps To Reproduce

1. Launch any game (launch parameters - DXVK_HDR=1 PROTON_LOG=1 gamescope --force-grab-cursor --fullscreen -w 2560 -h 1440 -r 180 --hdr-enabled --hdr-debug-force-output %command%)
2. Wait for a second or two
3. Crash

The command is wrong, it should be: DXVK_HDR=1 PROTON_LOG=1 gamescope --force-grab-cursor --fullscreen -w 2560 -h 1440 -r 180 --hdr-enabled --hdr-debug-force-output -- %command%
