maxSwapchainSampleCount is 1 on Quest 2? No multisample swapchain images?

With deprecated Oculus API, it was possible to submit multisample textures.

 

Now, with OpenXR, xrEnumerateViewConfigurationViews() tells that maxSwapchainSampleCount is 1. It means it's impossible to create multisample swapchain images (XrSwapchainCreateInfo.sampleCount must be 1). Is that correct? So, the only option is to render to other multisample framebuffer, then do `blit` to swapchain image?

    I'm using 2 samples without any problems in my app.  4 works too.

    Using native OpenXR? After xrEnumerateViewConfigurationViews() call, what have you got in ((XrViewConfigurationView) view).maxSwapchainSampleCount?

     

    (I got 4 on PC and 1 on native Quest 2)

    I'm using native OpenXR via Rust wrapper.  maxSwapchainSampleCount equals 1.

      I can confirm that maxSwapchainSampleCount is still reporting 1! While I recognize that I could ignore this value, I'd prefer that it report an accurate value. Any chance we can we get the dev team to fix this?
