Clarification on QSGNode::preprocess()

It’s not a typo. I don’t understand what conditions cause seg faults when I delete scene nodes. I’m pretty confused in general on how to deal with the new scene graph stuff since there’s a separate render thread asynchronously doing stuff. If I have some custom opengl rendering in a QSGNode in the preprocess() call, will I get a seg fault when someone changes the QQuickView to another QML file and parts of my scene graph get deleted?
