Help! Unity app has multiple-second freeze on device only
Hi all,
We have a simple Unity Hololens app that involves creating a bunch of prefabs whenever a button is tapped. Unfortunately, the app visuals lock up entirely for up to several seconds, for random durations in either one or more periods, in the frames just after the tap - but only when running on the Hololens headset.
We thought the web request via Unity's WWW class might be responsible, and so added a caching solution to load all data from AssetBundles - still freezes on device.
We thought the object Instantiation might be the problem here, and so added an object pooling solution to instantiate the objects earlier - still freezes on device.
We've tried optimizing as per the official optimization articles, and by removing all spikes from the Unity profiler (making the app silky smooth in the Unity editor) - still freezes on device.
There's no audio, we're using "Simple" Unity quality settings, and we've also just tried calling HolographicSettings.SetFocusPointForFrame after looking for answers on this forum.
What else should we try to fix this problem? Thanks in advance!

And minutes after typing this out, we realized that the stuttering disappears when building to device in "Release" rather than "Debug" mode. Leaving this up for posterity regardless.
