MSAA is not applied when 'Depth Submission Mode' is set to 16 bit and using Vulkan Graphics API

1.17.X

As Designed

Thank you for reporting a bug to Unity. After reviewing the behavior, we've confirmed it aligns with the current design and intended use of the feature. We understand this may differ from your expectations or workflow. After investigating, MSAA is being applied correctly, however the reduced depth precision introduced by submitting the depth buffer as only 16 bit is causing the artifacts. 16 bit depth submission should only be used if the rendering bandwidth is needed. However, if 16 bit depth is needed a solution that will help mitigate the problem would be to increase the near and far plane maximums in order to increase overall depth precision in scenes. We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.
