Yes, you're right. Actually now I was thinking that this change actually does 
nothing except adding some "delay" in between the show and exec.

https://github.com/qtproject/qtbase/blob/17d6b2d1f02e5f679008d97036befd713025a0f2/src/widgets/dialogs/qdialog.cpp#L533

Now I can reproduce the problem with following code snippet.

int main(int argc, char* argv[]) {
    QApplication app(argc, argv);

    QDialog a;
    a.show();
    a.hide();
    a.exec();
    return 0;
}

Probably worth report to Qt.
