Validation layers give some messages

[jaebaek]

I ran tutorial05 while turned on the following layers:

07-10 11:07:46.493 5944 5959 I Vulkan-Tutorial05: 5 layers exists
07-10 11:07:46.494 5944 5959 I Vulkan-Tutorial05: VK_LAYER_LUNARG_parameter_validation
07-10 11:07:46.494 5944 5959 I Vulkan-Tutorial05: VK_LAYER_GOOGLE_unique_objects

07-10 11:07:46.494 5944 5959 I Vulkan-Tutorial05: VK_LAYER_LUNARG_object_tracker

They gave the following messages:

I just put the code how I turned on the validation layer:

thanks fo filing the issue, will take a look.

I did see errors from your app; when I added the validation layers to the tutorial5 with the same ways as tutorial2, it does not show up those errors somehow. One thing is: the code here are from the original Vulkan release days ( 2016 ), validation layers now does not have to be added for device, but that would not account for the deficits. The layer order suppose to be re-ordered so that

  // VK_LAYER_GOOGLE_unique_objects need to be after
  // VK_LAYER_LUNARG_core_validation
  // VK_GOOGLE_THREADING_LAYER better to be the very first one

I will look at the errors and fix them accordingly in app
