I can confirm this is still an issue.
My setup is:
Ubuntu 18.04
MSI GE60
Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
Intel HD 4600 + GeForce GTX 760M
nvidia-driver-396 (396.54-0ubuntu0~gpu18.04.1 from grphics-drivers PPA)
nvidia-prime for switching cards
With nvidia-drm.modeset=1 until some vulkan app is run as root the
vulkaninfo crashes like this:

AppDumpSurfaceFormats: Assertion `!err' failed.
Aborted (core dumped)
I have added some logs to vulkaninfo to check what is the value of
vkGetPhysicalDeviceSurfaceFormatsKHR function that leads to abort and it is: -3
(VK_ERROR_INITIALIZATION_FAILED)
According to specification this error value should not be returned by this
function but here it is...
On nvidia forum there is similar issue reported but unfortunately
without conclusion:
