Memory leak with InstantTracker instantiated multiple times

unity: 2017.1.1 Wikitude 7.0.0

We have a scene with a map and a scene with AR gameplay, in our game we go between these scenes during the gameplay.

When we go into the AR scene we:


If we go between the scenes 13 times on my iphone6 I get:

WARNING -> applicationDidReceiveMemoryWarning()

Message from debugger: Terminated due to memory issue

On my Nexus5 it takes 23 times and then freezes.

Attached is the memory profile from xcode it appears that 18M is being launched with each cycle.

I cannot see this leak reported in either the Unity profiler or ios instruments.

If I do not create the Instant Tracker this doesn't happen.

Is there some way of fixing this, some shut down call before exiting my tracking scene perhaps ?


This issue should be fixed in the 7.1.0 release.

If you still have any issues, please let us know.

Best regards,


This problem persist as described in 7.1.0
