I have found out just now that if I run anything Vulkan as root (e.g. sudo vulkan-smoketest), IT WORKS! And if I then run it without sudo, IT STILL WORKS!

At this point I have no idea what is going on, nor why this doesn't affect lightdm nor sddm.
It seems the affected package is indeed nvidia-graphics-drivers-390. Since it is proprietary, I'll ask in the NVIDIA Devtalk forums.
