Visual Bugs on Linux with Vulkan renderer and Proton-7.0-rc3-GE-1 apparently also win10

Hi,
I just downloaded the new Proton 7.0rc3 GE, started BeamNG, and was wondering if maybe the vulkan renderer works with Proton 7, as it (for me) didn't work with Proton 6.
Everything worked fine, FPS in the menu was at the beginning a bit lower (~300fps) as with DX11, but after a few seconds I had ~1100fps in the menu.
Loading into Gridmap V2 took a bit longer as usual I think.
I was surprised when I saw that the Game didn't crash immediately after the loading screen as it happened with Proton 6, but there were severe Visual Bugs, see for yourself:
And no, I didn't blur things afterwards, this is how it looked like.
I thought that the blur could be because of DOF, so I disabled it, which worked fine, but the image was still blurry, so I wanted to enable it again, which looked like it worked, but after a few seconds the game crashed (you can see the crash report window on the left of the image).
But before that, I also tried driving a bit around, which worked, camera also worked fine.
What also surprised me was that the menus weren't blurred at all, as you can also see in the image.

P.S.: With DXVK and same Proton-7.0rc3-GE-1 everthing seems to work fine (except some other bugs like black terrain which I "fixed" with Snoutie's "fix", and Visual bugs with water, but they aren't that bad, I'll post another thread about that in a few Minutes and link it here.

 

This happens with vulkan for me on both Win10 and Linux Proton Exp
