    I hope this is getting prioritised as it is crippling.

    I'm also experiencing this consistently, making the editor fairly unusable.
    Seen in both 2021.2 and 2022.1

    Can confirm, this is so annoying.. has something to do with the throttling setting. Tho deactivating that (No throttling) doesn't seem to work
