  1. Resolution Note:

    This bug is no longer re-producing on Pixel 6 with Android 14 hence closing. Also checked on M34 and A34 Samsung phones with Mali GPU's, does not happen repo either.

    Please re-open this if it happens again in a different scenario.

    As a result of the operation of the project under development at hand,
    A similar phenomenon occurred on Pixel6 with Graphics Jobs=OFF. (Unity2021.3.24f1)

    Due to the contract, it is not possible to submit the project itself.
    Unfortunately, I have not been able to create a sample that can be reproduced.

    The following fix will complete Android build with Unity 2022.3.5.
    However, the only problem that flickers is the glass part of the goggles when "Benches" is about 100 or more. (when running on Pixel 6a)

    (1) private void SetTonemap(bool tonemapIsActive) function in LookdevSingleScene.cs :
    "tonemapIsActive" always set to false.

    (2) In CustomRealtimeLights.hlsl , Add follow code before of GetMeshRenderingLightLayer()
    #ifndef DEFAULT_LIGHT_LAYERS
    #define DEFAULT_LIGHT_LAYERS 0
    #endif
