Just noticed that my image marker content is lagging heavily with iOS 11.4 and extended tracking/device tracker enabled.
Console shows that "OnTrackableStateChanged" is called a couple of times a second switching from EXTENDED_TRACKED to TRACKED and vice versa, even if you just hold still focusing the marker. Each time the callback is called, I get a nasty & heavy framedrop.
Has this reported elsewhere? Is there a fix?
With devices running iOS 11.2 I don't get these issues...
All the best,
- Vuforia 7.2.23
- Unity 2018.2.2f1 + 2018.2.6f1
- XCode 9.4.1
