[AR Foundation] Only one in a few instances of the same build is running correctly

Unity Engine

Hello all,

I’ve currently run into an issue - I need to restart my application (same apk build) that is using AR Foundation and image tracking a few times, until it runs smoothly. What might be the cause? Using AR Foundation 4.1.7, Unity 2021.1.7f1. Disabling/enabling multithread rendering doesnt help. Redmi Note 9 pro.
I’ve prepared video comparison:

Regular (flashing model, wrong model orientation):

Random instance of the same app after ~15 restarts (runs perfectly and smoothly af):

Next instance still behaves like regular one and needs restarting until randomly works for one run.

Thanks for help!
