    Still having this issue in 5.3.1p1. Explained more in this thread about the issue. Apparently for some unknown reason HandleUtility.INTERNAL_Call_Internal_PickClosestGO Makes hundreds of thousands calls to a couple of methods when an object is attempted to be selected.

    Yes this happens to me All the time!
    I select something from a scene (using mouse in scene view), where the selection will pass through a number of objects - selecting just one with nothing behind it seems to be more reliable.
    Then the editor just hangs, between 30seconds and up to 5 minutes! Waiting eventually selects the object.. but so much time is lost!
    So annoying!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Happens on 5.3.1.f1

    Please re-open this issue. It is not resolved and is still reproducible in both 5.3.1 and 5.3.1p1.

    I have the same issue with 5.2.2, so upgraded to 5.24 same issue. On selecting an object in the scene view is fine, then select another it freezes for 5 minutes, eating up memory until I end task it. Can't move to 5.3 or 5.3.1 as the frame rate is really bad. I lose about 40-50 fps from my project
