[GPU PLM][macOS] Baking is stuck on 'Finalizing Bake' stage when baking on OSX with AMD GPU

Progressive Lightmapper


Was trying to debug using the attached project, and end up in a state where I no longer can bake (and no errors or breakpoints hitting).

Seen on 20.1.0a17.2009 on OSX Mojave:
AMD Radeon R9 M370X 2 GB
Intel Iris Pro 1536 MB

The steps are:

1. Download this project:
2. Open the project on OSX;
3. In the Lighting window press Generate Lighting button and observe that the baking is stuck in the neverending loop.


Be in auto on the scene.
1. Let GPU finish
2. Change to smaller values (8/8/8) for samples and let finish
3. Change to CPU and let finish
4. Change to GPU and it is stuck on Finialize
5. Change to CPU or Enlighten and it just says "Baking...".
6. The state is dead and the editor has to be restarted.

- Reproducible only on OSX with AMD GPU; not reproducible on Windows with NVIDIA GPU;
- Please note that this bug is an absolute blocker for the GPU PLM functionality on OSX at the moment.
- Reproducible in 2020.1.0a16;
- Not reproducible in 2019.3.0f3.
