398896ms when isolating an entity for the first time.

Unity Engine
1

Hello ! I’m using the isolate entity feature ( Scene Visibility Tools - Info and Discussion Thread ) and every time I use it for the first time (either first time in a scene, or first time per prefab I’m editing) I get 5+ minutes lag spikes.
It gets stuck in MemoryManager.FallbackAllocations.
Can someone help me investigate what could be the cause of this ?
Thanks.

I mean the profiler show all the time spent on Application.Tick’s self ms column, in deep profile! That’s unusual, usually deep profile manages to show where the time is spent.

I’d post this in the Scene Visibility Tools thread you linked, as that’ll ping the developers of the feature.
