[BUG] Proton has shader errors unless ran with X11 once

[zezba9000]

So I've seen this issue happen on multiple systems. Where Proton has shader errors unless Steam is invoked under X11 once with xstart steam.
After doing this I never have to do it again and Steam games like "Limbo" start working with Proton without issues.

The devices I've seen this on are.

• System76 Pangolin (AMD Ryzen 7 7735U) laptop running PopOS 22.04
• MSI-Claw: custom Arch distro I'm making
• Some other AMD devices using ChimeraOS

This is an incredibly odd bug. I'm guessing given Steams/Protons history with X11 its not generating some config if only ran under Wayland.

I've also reported this here as I'm not sure which project is actually the underlining issue.
