How to reproduce:
1. Create and open a new 3D URP project
2. Create a Plane and a Rendering>URP Decal Projector in the Hierarchy
3. Select the URP Decal Projector, and in the Inspector, press “Open“
4. In URP settings, change the Rendering Path to “Deferred“
5. Add the “Decal“ Renderer Feature at the bottom
6. In the Decal Renderer Feature, change the Technique to “Screen Space“
7. Observe the Scene view

Expected result: A square decal is seen rendered on the Plane
Actual result: No decal is seen rendered on the Plane

Reproducible in: 6000.1.0a2, 6000.1.14f1, 6000.2.0b13, 6000.3.0a3
Not reproducible in: 6000.0.54f1, 6000.1.0a1

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- Decals do not render in Deferred+ Render Mode as well
- If the project is downgraded to 6000.1.0a9 from a later version, the Decal will fix itself, and will stay fixed even after upgrading
- Similar behavior can be observed when upgrading from 6000.1.0a1 to 6000.1.0a2 (the bug will fix itself)
