Steps to reproduce:

1. Open a new scene and add some static geometry
2. Navigate to Lighting Settings, and make sure that Lightmapper is set to Progressive GPU
3. Bake the lighting
4. Navigate to the Scene viewport and select the Texel Validity debug view
5. Notice that the view is predominantly orange and does not show any relevant info

Notes:

- The issue is mitigated if a user bakes with CPU PLM first
- The issue is also mitigated if Texel Validity view is open while baking using GPU PLM
