Symptoms

X-Plane 12 on Steam does not work when trying to use it with Proton, it crashes and mentions it's missing libraries on Vulkan. Because of this, i will never be able to use the VR mode the game comes with.
It starts in OpenGL but crashes shortly after the loading screen appears.
I have tried using it on my laptop that has Linux Mint and it does start with OpenGL, loads and it's playable, but the Vulkan issue is still there.

I then bought another copy but it is a linux installer from the X-plane Laminar Studios website and it works fine on Fedora, I believe it is running with OpenGL.

Reproduction

Install any version of Fedora (I have tried it with 38, 39 and 40), the OpenGL does not work on it. Try proton with Fedora or Linux Mint and you get an error for missing vulkan libraries or plugins.
