GPU Lightmapper produces invalid texels in a certain scene

Global Illumination

-

Steps to reproduce:

1. Open the scene ArtPresent.
2. Bake GI using the GPU Progressive Lightmapper (options don't matter).
3. Notice that most texels in the scene are invalidated.

Notes:

- Switch to Texel Validity visualisation in the Scene View. Observe that a big amount of pixels in the scene are invalid.
- Clearing the GI Cache, clearing Baked Data for the scene or manually deleting the folder that contains it don't fix the issue. The only way to fix the issue is to transfer the gameobjects to a fresh new scene.
