    We move our characters with animations and in the IK loop.
    When they hold items with cloth attached they jitter all over when moving in various ways. this was not present in 2018.4.
    We switched our project recently to 2020.3 LTS, and this is a terrible problem.
    It's slightly better by putting the animator update mode to Animate Physics, but that adds new issues.. this is also costing performance..
    We need cloth to just work.. not be broken all the time.

    Clothes are unusable on Unity 2019.4, totally shaking together with the animator. I think moving to another system than unity clothes is the best idea
