    Still persists: Unity 6000.1.0f1

    1. AsyncGPUReadback.RequestIntoNativeArray
    2. Read in jobs in next frame after Callback is triggered <- Mandatory to trigger an error later
    3. AsyncGPUReadback.RequestIntoNativeArray -> Error

    During consequence calls after receiving callback:
    AsyncGPUReadback - NativeArray does not have read/write access
    UnityEngine.Rendering.AsyncGPUReadback:RequestIntoNativeArray<Unity.Mathematics.float3>
    AsyncGPUReadback - NativeArray should not be undisposable
    UnityEngine.Rendering.AsyncGPUReadback:RequestIntoNativeArray<Unity.Mathematics.float3>

    And on Dispose during Destroy
    InvalidOperationException: The Unity.Collections.NativeArray1[Unity.Mathematics.float3] has been set to undisposable and cannot be deallocated.
    -> And a leak at the end as dispose failed.

    Am getting this error on Unity 6000.0.19f1

    InvalidOperationException: The Unity.Collections.NativeArray`1[GPUDecalUtils+ReadableVertex] can no longer be accessed, since its owner has been invalidated. You can simply Dispose() the container and create a new one.

    This is still happening when trying to read a rendertexture to a nativearray in 2021.3.15f1.

    "Hi all, the fix has finally landed in 2022.1.0a12.
    This means the backports will now be unblocked and can land in the main releases."
