    Description

      After upgrade to Qt6.5.31, I face a problem: In my QMainWindow, it contains a QStackedWidget. When I add a QWidget (named exampleWidget) which contains a QWebEngineView to the stacked widget, the QMainWindow will be recreated.

      With some debug, I found that the original surface type of the mainwindow is raster surface. But when add the QWebEngineView which surface type is Direct3D, this will cause the mainwindow be recreated.
