How to reproduce:
1. Open the “HeavyObjectBug.zip“ project
2. Open the “TestScene“
3. Enter Play Mode
4. Observe the Game view
Expected results: The heavy GameObject does not stutter on collision with light GameObjects
Actual results: the heavy GameObject stutters on collision with light GameObjects

In my tests, the issue is present even when the mass ratio is 1:1. Check out my latest forum post for a video illustrating the issue with various mass ratios.
