    Hey,

    in the recent Unity versions the scene view started getting really slow whenever Unity is open for some time (5+ minutes).

    I profiled the editor and it appears as if there is a massive UIElements overhead. Weird Thing is there is no non-standard UI in the scene except for a couple of gizmos. As soon as I close the scene view the overhead is gone (as you can clearly see in the profiler).

    With this issue Unity is basically unusable since you have to restart it every couple of minutes.

    Bug report is submitted (Case 1233795)

    Any ideas what's going on here? Thanks for the help!
