[AMD] [DX11] Additional lights are broken when Spotlight is added to the Scene

--

-

Reproduction steps:
1. Open the attached project "My project"
2. Make sure that the Editor is using DX11
3. Switch platform to the Android
4. Right-click on the Hierarchy, hover over Light, and click Spotlight

Expected result: Lights with color stay colored
Actual result: Lights with color lose color

_Reproducible with: 2022.1.0a13, 2022.2.17f1, 2023.1.0a1, 2023.2.0a11, 2023.3.0a5_
_Not reproducible with: 2020.3.47f1, 2021.3.23f1, 2022.1.0a12, 2023.1.0a2, 2023.1.0b13_

Reproducible on: Windows 10 Enterprise 21H2

Notes:
- When you put more than 1 additional light on the Scene, all lights copy properties from one (Color, type)
- More info in the Unity Forum: [https://forum.unity.com/threads/so-tired-because-regressions-after-each-update.1348976/]
- *Android Platform must be selected to reproduce*
- *Direct3D11 must be selected to reproduce*
- When DX12 is selected the 2 lights that are already in the Scene are green and red, but when switched to DX11 they both become green
- *AMD GPU required to reproduce, doesn't repro on NVidia*

 

Workaround: Use another rendering backend than DX11. Both DX12, Vulkan and OpenGL seem to work fine.
