    Description

      If a QMacCocoaViewContainer object with a custom NSView and a QOpenGLWidget are put into a QSplitter, when you drag the splitter, a Cocoa exception traceback is shown.

      If you replace the QOpenGLWidget with a QWebEngineView, you get a hard crash.

      These are the warnings and traceback shown:
