[HDRP][DLSS] Checkerboard-like artifacts appear on the edges when DLSS is enabled and set to Maximum Quality
How to reproduce:
1. Open the user's attached "U - BUGREPORT [DLSS arifacts]" project
2. Open the Scene "Bugreport scene"
3. Enter the Play Mode In the Hierarchy select the "Main Camera"
4. In the Inspector under the Camera->Rendering change the DLSS Mode to "Maximum Quality"
5. Enable/disable DLSS and compare the Game view results
Expected results: When DLSS is enabled the edges do not have checkerboard-like artifacts
Actual results: When the DLSS is enabled the edges have checkerboard-like artifacts
Reproducible with: 12.0.0 (2021.2.0b4, 2022.1.0a2)
Could not test with: 11.0.0 (2021.1.15f1) and earlier because DLSS is not available

Resolution Note:
the problem in this particular scene is that the "Use Optimal Settings checkbox" is choosing a resolution percentage that is too small. You can see the input resolution vs output resolution if you go into Window > Analysis > Rendering Debugger > Rendering, and in there look at the DLSS Slot table. You will see an input resolution and output resolution. To help mitigate these artifacts:
* Uncheck the "Use Optimal Settings" checkbox in your camera
* Your game window, choose a resolution (instead of free aspect, pick say QHD or 4k)
* In your Dynamic Resolution Settings inside your quality asset, force a percentage no lesser than 70.7 (that's around 50% of your pixels (70.7 * 70.7)
When your input resolution is very low, such as 43% of your pixels (as in your example) expect to see instability and some artifacts due to edges in geometry not converging properly.
