[Quest 3][Vulkan][URP] - Some assets render incorrectly on quest 3 hmd

-

Description

When testing the functionality of Quest 3 in ARFoundation samples, I encountered an issue where URP builds across 2022.3, 2023.1, and 2023.2 Unity Editor versions failed to work properly. Specifically, the left eye displayed plane meshes that overlapped in a grid pattern, which remained fixed to the user's view. On the other hand, the right eye rendered the planes correctly.

 

In built-in the planes in the project rendered as expected in both eyes. This did not repro on Quest 2 or Quest pro.

This does not repro using GLES only Vulkan graphics API

Repro Steps:

  1. Open the provided project
  2. Build and run the project.
  3. Observe the behavior.

Observed Behavior: 

  • The plane meshes rendered differently in each eye.
  • The overlapping of plane meshes in the left eye resulted in an unusable experience.

Expected Behavior: 

  • Plane meshes should render the same way in both eyes.
  1. Resolution Note:

    The issue is closed for the time being as the team is unable to prioritize fixing this bug. There are a number of reasons we make this decision, including the impact and severity of the issue across our user and customer base, and the possibility that future plans may solve the problem in a different way, or that a workaround for the bug may be available.
