    Description

      See attached video: Repeatedly untabbifying an undocked, tabbed QDockWidget and putting it back generates leftover container widgets and crashes after a while.

       

      I modified the example at qtbase/tests/manual/examples/widgets/mainwindows/dockwidgets by setting these options in the MainWindow constructor:

       

      setDockOptions((QMainWindow::DockOptions)(AllowNestedDocks | AllowTabbedDocks | GroupedDragging));

       

      This report is a continuation of https://bugreports.qt.io/browse/QTBUG-114542 which was supposedly fixed in 6.6.0.
