Proton 8 and Proton Experimental will not launch anything

[pippaine]

Describe the bug

When selecting Proton Experimental or any variant of Proton 8 (incl. 8GE) as the compatibility layer, any game I have tried will fail to launch. This issue occurs in both gaming mode and desktop mode.

What did you expect to happen?

Compatible games should run

Extra information or context

This issue does not occur on my Steam Deck LCD with SteamOS

Workaround:

• Use a version of Proton 7 or lower.

I'm pretty sure I have this same issue on an HTPC with a RDNA2 GPU connected to an HDR TV. If HDR is enabled, any game using Proton will fail to launch.

/usr/include/vkroots.h: 13981: void vkroots::tables::CreateDispatchTable(PFN_vkGetInstancePocAddr, PFN_GetPhysicalDeviceProcAddr, VkInstance): Assertion 'res == VK_SUCCESS' failed. is the last thing printed in the console before the game exits.

Try adding DXVK_HDR=0 and ENABLE_GAMESCOPE_WSI=0 to /etc/environment and see if that fixes it.

[nadiaholmquist]

Doesn't seem to work around it in my case.
