Repro:

1. Download and import the attached repro project
2. Open the Scene SampleScene.unity
3. Ensure the LightingSettingsUltra settings asset is being used
4. Ensure that Radeon Pro is selected for the Direct and Indirect denoisers
5. Hit Generate

Observed:

- Lightmaps will appear with disco colours and other corruption as can be seen in the supplied screenshot.

Expected:

- Lightmaps should be smooth, denoised and output should be plausible.

Notes:

- If the repro steps above are repeated using OpenImage or Optix, the corruptions and discolourations are not visible in this way.
