Materials render incorrect color when using the "require native16bit" pragma directive

Unity: Shader System

2023.3.X

2023.2.X

2022.3.X

6.0.X

Using 16-bit types in a constant buffer was never supported, so the issue is not a regression. This may be added in the future, however.

Closing as Won't fix due to 2023.2 reaching it's EOL.

How to reproduce:
1. Open the “DXC16BitIssue“ project
2. Open the “SampleScene”
3. Open the Scene view window
4. Observe the “16bit” GameObject

Expected result: The “16bit” GameObject is red
Actual result: The “16bit” GameObject is black

Reproduced with: 2022.2.0a1, 2022.3.15f1, 2023.2.3f1, 2023.3.0a17
Not reproduced with: 2021.3.33f1 2022.1.0a16

Reproduced on: Windows 11
Not reproduced on: No other environment tested

Notes:
1. Also reproducible in Player
2. In the 2023.3 stream the “16bit” GameObject is green
