Hi, Thank you for sharing this tutorial, it's very helpful. I added code locally to enable vulkan validation layers, including synchronization validation.
It seems that there's various validation errors when running Chapter_6_1_Multiview.
I'm running the app on PC, via Oculus Link, rendering to a Quest 2 headset.
Would be great if you can enable validation layers and address any validation issues. I'm currently using Vulkan SDK version 275.
Here's the errors I get on my machine:
