    Most people do not move their projects to the latest release because there is always something else that gets broken.<a href="">Outlook Telefoonnummer</a>

    Man I made such a fuss and it turns out the issue was my own.

    Still not fixed in 2018.3b, i was hoping something might get fixed with the new PhysX version but nope.

    A few months ago I submitted a bug report with a sample project illustrating that the issue ONLY happens when the framerate is not steady, but I got tired of trying to explain this to the QA tester and gave up.

    If you want this fixed, contact Unity as well.

    Seems to be fixed in 2018.2.0f1. Hope they patch it in the LTS release too.

    Seems slightly better, but still apparent in 2018.1.7f1.

    9 months since this was reported and you still can't use anything newer than 2017.1.2 if you want to use Interpolated rigidbodies on iOS.

    There seems to be some conjecture about it actually being fixed in 2018.2 and when that will actually be released.

    Most people do not move their projects to the latest release because there is always something else that gets broken.

    Anybody can confirm that "Fixed in Unity 2018.2" is real ? 2018.2.0b10 ?
