False-positive message with swapchan, but without WSI

[Neko-tech-priest]

Environment

• OS: Linux
• GPU and driver version: RX 6600XT, Mesa 25.3.3
• Options enabled: Sumbit time validation, AMD-specific, Performance

Describe the Issue
Without VK_KHR_swapchain validation layer don't know when frame changed and thinking what i bind the same pipeline again, but i have vkEndCommandBuffer and vkQueueSubmit2 every frame with vkWaitForFences waiting, with WSI implementation was fine

Expected behavior
Nothing messages

Instead, i have message:

Validation Performance Warning: [ BestPractices-Pipeline-SortAndBind ] | MessageID = 0x6d0c146d
vkCmdBindPipeline(): [AMD] [NVIDIA] Pipeline VkPipeline 0x380000000038 was bound twice in the frame. Keep pipeline state changes to a minimum, for example, by sorting draw calls by pipeline.

Additional context
I make pure Wayland application, without libwayland-client

So looking at the Best Practice code, the logic is simply

• at vkCmdBindPipeline check if same pipeline was bound twice (if not add)
• at vkQueuePresentKHR reset

So I just realized looking at this, this is not even checking if graphics

@Neko-tech-priest is your Pipeline a compute pipeline?

[Neko-tech-priest]

@spencer-lunarg No, it's graphics pipeline
As i said, vkCmdBindPipeline bind only once(even in render frame it's called only 1 time, no other pipelines) and vkQueuePresentKHR require VK_KHR_swapchain, what impossible use without WSI
