I have managed to replicate the issue.
Have a barrier set to 100x100x100 size and then in uefn change the size from 1.0 scale to like 3.0 scale then teleport inside the barrier and itll not show all the time.
Hope this helps diagnosing the issues
I’ve tried these 2 things and they have no effect
No world streaming
never distance cull
I think its something with the render distance for sure
