VRChat in SteamVR mode results in a Unity crash when running in Proton Experimental, but not in Proton 8.0. This is the "Crashes while logging in³" scenario described in @digitalf0x 's testing reports from the main issue thread for VRChat.

My settings:

  • AMD GPU
  • Wayland
  • SteamVR (rolled back to 1.27.5)
  • VRChat latest stable (2023.4.1)
  • Proton Experimental - Unity crash
  • Proton 8.0 - works fine

I bisected Proton, this is the first bad commit.
"vrclient: Wrap parameters in structures."
