Ambient Light Occlusion is not baked properly in a grid based scene
How to reproduce:
1. Open attached project
2. Open scene OcclusionBug.unity
- Notice how some of the squares are darker in the Shaded view. Switching to Directionality or Irradiance makes those squares more pronounced.
- Editing Ambient Intensity (in Lighting -> Scene), and setting it to zero makes the shading seamless (but without any Ambient Lighting)
Here is what the issue looks like:
Ambient Intensity set to 0: http://screencast.com/t/hFmfZaNFaqq0
Ambient Intensity set to 1: http://screencast.com/t/Ys35LVi9aG

The reason you get the dark squares is that the cube (the ground) sees a lot of backfacing polygons (the trees). You can fix this by assigning a custom Lightmap Parameters and setting a lower Backface Tolerance.
