    I'm so happy to share this with you that can read / see this now. When I started trading binary and forex a few months ago, I really didn't have the necessary tools to trade and I lost a lot until I met Pablo Martinez who taught me all about market psychology as he managed my account for me. Today I am grateful to him for his great offer and help because it really changed my financial situation with an investment capital of $1500 and now I'm earning around $35,500 - $30,000 profits per week. Here is his WhatsApp no: +44 7520 636249 or his email address:

    I'm on 2021.2.17f1 and can totally see some serious regression after being yesterday on 2021.1.28f1...
    I can drag a gameobject on the scene inspector to reparent it to another and wait there for seconds... even sometimes if the mouse is standing still it won't trigger any sort of action update, the UI stays there doing none of the reparenting until the mouse is flicked (which could also make the gameobject end somewhere else).

    Would a video of this help? How can I share it? Should I create a thread and put the things there?

    Updated my project from 2021.2.1 to 2021.2.2 and the worst UI delays seem to have gone. Selecting hierarchy items is no longer slow and inspector fields now update as expected.

    Just wanted to link to this other issue which is maybe possibly the same problem:

    2021.2.2f1 is not released yet, but I'll re-test this once it is.

    Very much reproducible. Duplicate of existing issue listed on 2021.2.0 that is supposedly going to be fixed in 2021.2.2, but is still very active and do you have any Mac developers on your team at all?
