sporadic Crash in QML application

A QML based application crash sporadically but frequently. This mostly happens when window returns from being hidden back to "visible". I.e. when users re-activate the running application. In many cases the crash happened right after the computer was woken up from hibernation.

This has been mainly happening on Mac, On windows and Linux it seems to be okay.
Attached is the stack trace.
Unfortunately there is no reproducer available to reproduce it. Hope Stack trace gives some clue.
