I have never seen this issue, so it's hard to tell anything about it. I may suggest you to try debugging further and try to find out why Python and C++ programs behave differently. Also, you may try to contact upstream PyQt [1] or Qt [2]. [1]: https://www.riverbankcomputing.com/mailman/listinfo/pyqt [2]: https://bugreports.qt.io/ -- Dmitry Shachnev
