Vulkan Validation Errors when clearing the Screen (hello-windows example)

[sotrh]

Description
Running a render pass just to clear the screen causes a bunch of validation errors every frame. I found this while migrating my tutorial to 0.10, but I'm seeing this on the hello-windows example found on this repo.

Repro steps
You can find my code at https://github.com/sotrh/learn-wgpu/tree/0.10/code/beginner/tutorial2-swapchain, but running the hello-windows example works as well.

Expected vs observed behavior
Creating a render pass to clear the screen, then dropping it shouldn't cause these validation errors.

From the links, you're using sdk 1.2.148 (latest is 1.2.182 iirc), wgpu 0.10 needs recent validation layers to not have false positives, so hopefully updating will fix this.

Ok I'll try that

That's working for me. I'll add that to my tutorial.
