QWebEngineView: a view renders the contents of another view rather than its own
In my application, I have two docked windows that each contain an instance of
QWebEngineView. Now, everything works as expected on my development Windows 10 (virtual) machine, as shown here.
However, after having deployed my application on a vanilla Windows 7 (virtual) machine, I can see both windows rendering the same thing. One of them renders what it should be rendering, but the other basically renders a 'screenshot' of the other window (see here and here).
Would anyone have any idea as why this is happening?
