Can confirm the jittering behavior. Last known good commit is e60c49ecf06815039137c98f86a7198d6ee81e14 from November 25, 2018. (that time i last merged 2.8 into temp-fracture-modifier-2.8, and it works in the branch)
So i am trying to git bisect now from there till HEAD to find the faulty commit... I keep you posted.
