VUID-VkCopyImageInfo2-srcImage-01548(ERROR / SPEC): msgNum: -1018313304 - Validation Error: [ VUID-VkCopyImageInfo2-srcImage-01548 ] Objects: VkCommandBuffer 0x5f788e5c6ec0, VkImage 0x8168780000000092, VkImage 0x8bada20000000098 | MessageID = 0xc34dc5a8
vkCmdCopyImage2(): pCopyImageInfo srcImage format (VK_FORMAT_D32_SFLOAT_S8_UINT) is not size-compatible with dstImage format (VK_FORMAT_R8_UINT). VK_FORMAT_D32_SFLOAT_S8_UINT is a depth/stencil and VK_FORMAT_R8_UINT is color (this is only allowed with a certain set of formats during image copy with VK_KHR_maintenance8).
The Vulkan spec states: If the VkFormat of each of srcImage and dstImage is not a multi-planar format, the VkFormat of each of srcImage and dstImage must be size-compatible (https://docs.vulkan.org/spec/latest/chapters/copies.html#VUID-VkCopyImageInfo2-srcImage-01548)

vkCmdCopyImage2(): pCopyImageInfo->pRegions[0].dstSubresource.aspectMask is VK_IMAGE_ASPECT_COLOR_BIT and srcSubresource.aspectMask is (VK_IMAGE_ASPECT_COLOR_BIT), but the src depth/stencil format (VK_FORMAT_D32_SFLOAT_S8_UINT) is not compatible with the dst color format (VK_FORMAT_R8_UINT).
The Vulkan spec states: If srcSubresource.aspectMask is VK_IMAGE_ASPECT_DEPTH_BIT or VK_IMAGE_ASPECT_STENCIL_BIT and dstSubresource.aspectMask is VK_IMAGE_ASPECT_COLOR_BIT, then the VkFormat values of srcImage and dstImage must be compatible according to the list of compatible depth-stencil and color formats (https://docs.vulkan.org/spec/latest/chapters/copies.html#VUID-VkCopyImageInfo2-srcSubresource-10212)
