[Technique] World tracking performance is being affected by resource constraints

Hello,


Since iOS 12 and ARKIT 2.0, with nothing changed in my code, I get the following message, when placing a scn object in AR :


[Technique] World tracking performance is being affected by resource constraints


Is it a known bug in the framework ? It was running smoothly with ARKit 1.5, and this suddenly appeared since 2.0. And I'm not doing anything fancy.


Thanks for the help !
