How to reproduce:
1. Open user's attached project ("RigidBodyCollisionDetectionChange.zip") using the EnvIronman VM (more information in Edit)
2. Open the sample scene
3. Enter Play mode
4. Observe where the green Cube GameObjects collide

Expected result: Green Cube GameObjects collide exactly like the red Cube GameObjects
