Vulkan header updated 1.2.193 changed the behavior of vkGetInstanceProcAddr for global entrypoints. They used to always be returned regardless of the value of the instance paramtere. The spec was amended in this version to only allow querying global level entrypoints with a NULL instance. However, as to not break old applications, the new behavior is only applied if the instance passed in is both valid and minor version is greater than 1.2, which was when this change in behavior occurred. Only instances with a newer version will get the new behavior.
