In addition to my previous mail I've made couple of more tests... I've
decided to create new wheels using pyqt-bundle with qtbase version 5.14.2
and (5.15.0 beta - the one that contained this suspicious commit
https://github.com/qt/qtbase/commit/8f88a3962a )

On both attempts this bug was still present so I give up for now... if you
know if this bug has been solved please let me know the commit hash and
I'll give it a shot.
