Environment:Win 7 64bit / macOS 10.13, Qt 5.9.6
There is a very strange behavior with QDockWidget in my application after updating from Qt 5.6.2 to Qt 5.9.6.
1. Start the attached program (code is based on qt "dockwidgets" example)
2. Select View / Save state
3. Close the customers and the paragraph window (menu View) -> Screenshot1_ok.png, all ok
4. Select View / Restore state -> windows re-appear, all ok
5. Close the customers and the paragraph window (menu View) -> Screenshot2_failure.png, failure
With Qt 5.6.2, all is right ...
