      Description

      Sometimes editor asserts at shutdown:

      Assertion thrown C:\dev\qt\NDD\qt3ds1\src\Runtime\Source\Qt3DSFoundation\Source\foundation\TrackingAllocator.cpp(38): mAllocations.size() == 0

      Presumably this indicates a memory leak.

      It is difficult to repro, and I have not been able to find a reliable sequence but I suspect it is related to perspective view somehow.
