How to reproduce:
1. Create and open a new URP Sample project
2. Open any Scene
3. Go to Edit > Project Settings > Player
4. Set the “Direct3D12” Graphics API for Windows
5. Enable “Allow HDR Display Output“ and “Use HDR Display Output“ in the Project Settings
6. Select the “Assets/Settings/PC/PC_High“ Render Pipeline Asset
7. In the Inspector enable the “FSR 1.0“ in Quality > Upscaling Filter
8. Switch over to Scene view and then to Game view
9. Maximize the Game view window

Expected result: The render does not change
Actual results: Either the render is excessively saturated or is mostly black

Reproducible in: 2023.3.0a19, 6000.0.37f1, 6000.1.0b5, 6000.2.0a2
Not reproducible in: 2022.3.57f1, 2023.3.0a10
Could not test in: 2023.3.0a11 - 2023.3.0a18 (crash whenever the Graphics API is changed to DX12)

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

Notes:
- The issue does not seem to be reproducible in the HDRP Sample Project, so I suspect this is only a URP problem
- User reports that TAA might also have some significance for the reproduction, although I found it has no impact
- Not reproducible with DX11, other upscaling filters, or with HDR turned off
