    Description

      Hello,

      I am trying to create a kind of weather overlay system, and for this purpose I use particles in QML and Loaders to switch when necessary. However I faced a crash, and after a few days of investigations to try to reproduce systematically, I came out with a code that I attached here. I can't really tell where this is coming from. From what I see it is probably related to the fact that some QQuickItems-particles get deleted (maybe because of the Loader) and are still referenced in QQuickItemParticle.

      I attached the backtrace as well.

      Environment is Qt 5.11.0 with MinGW 5.3 under Windows 10, reproduced with two different computers. I couldn't confirm that this appears as well under Linux.

      Thanks,
      Louis
