[Bug] Flickering on AROcclusionManager Human Occlusion, when virtual asset is too complex

Unity bug report case number CASE IN-56139 and CASE IN-56140

(its duplicated because the first has more data but crashed the uploader so I didn't know if it was sent, but now I received two emails)

Describe the bug Human Segmentation provided by AROcclusionManager seem to be flickering, if there is an asset behind that has too many vertices.

To Reproduce Steps to reproduce the behavior: Create an AROcclusionManager with human occlusion on, Environment occlusion off, and add a big asset with many vertices and triangles.

Expected behavior Human Should not be flickering.

Actual behavior Human is flickering.

hey @andyb-unity I think this was fixed.

i dont know if it was arkit 5.1.1 or maybe ios 17.1.2, but something fixed it, it does not happen anymore

Hm, an iOS fix I would guess. I don't think we've changed anything about iOS Occlusion for a year or more. Feel free to re-open this issue if you see it pop up again.
