Vulkan validation errors.

[Onhi]

I get vulkan validation error while using OpenXR.

For exemple:

VUID-VkImageCreateInfo-pNext-01443(ERROR / SPEC): msgNum: 416909302 - Validation Error: [ VUID-VkImageCreateInfo-pNext-01443 ] Object 0: handle = 0x2cda8774080, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0x18d987f6 | vkCreateImage: VkImageCreateInfo pNext chain includes VkExternalMemoryImageCreateInfo with handleTypes 16 but pCreateInfo->initialLayout is VK_IMAGE_LAYOUT_PREINITIALIZED. The Vulkan spec states: If the pNext chain includes a VkExternalMemoryImageCreateInfo or VkExternalMemoryImageCreateInfoNV structure whose handleTypes member is not 0, initialLayout must be VK_IMAGE_LAYOUT_UNDEFINED (https://vulkan.lunarg.com/doc/view/1.3.231.1/windows/1.3-extensions/vkspec.html#VUID-VkImageCreateInfo-pNext-01443)
    Objects: 1
       [0]  0x2cda8774080, type: 3, name: NULL

I'm still new to this so I get that this might not be from OpenXR but from the runtime I am using?

Does this happen with hello XR or just your own software?

[Onhi]

Yes, here are the ones I noticed running hello_xr.

I should also point out that I could not find where vkDestroyDevice is called in hello_xr. This is another line that triggers a validation error in my own software.

VUID-vkDestroyDevice-device-00378(ERROR / SPEC): msgNum: 1901072314 - Validation Error: [ VUID-vkDestroyDevice-device-00378 ] Object 0: handle = 0x1b28114da10, type = VK_OBJECT_TYPE_DEVICE; Object 1: handle = 0x1b2d9ff4e80, type = VK_OBJECT_TYPE_COMMAND_BUFFER; | MessageID = 0x71500fba | OBJ ERROR : For VkDevice 0x1b28114da10[], VkCommandBuffer 0x1b2d9ff4e80[] has not been destroyed.
