    well my "theory" is that
    if QAxWidget is assigned to a parent before FramelessWindowHint
    then bug comes.

    @mrjj Then the solution is not to create QAxWidget in the constructor?

      Well I assume u tested that ?
      Create it after setupUI and FramelessWindowHint does not make it work ?

      If no, you can try with the showEvent
      void maiwinxx::showEvent( QShowEvent* event ) {
      QMainwindxx::showEvent( event );

      // create it here.

      }

          Hi, np. That was what i wanted to test.

          So if we create it before windows is fully shown we get bug?

          But if you create in button_click , it works?

              very strange!
              I though showEvent would been same as clicked.
              Try timer so that we first create after window fully shown.

              // in constructor
              QTimer *timer = new QTimer(this);
              connect(timer, SIGNAL(timeout()), this, SLOT(nowcreate()));
              timer->start(4000);
              }

              void MainWindow::nowcreate() << add this to .h also
              {
              qDebug() << "nowcreate";
              // create here
              QAxWidget *Test = new QAxWidget(this);
              ..
              }

                  ok
                  so window must be fully shown to make it happy.
                  Good testing :)

                    @mrjj Thank you very much for your help! So show window, and then create a widget ... So still the question, it is a bug Qt or something else? The problem can be considered solved only in the bug tracker you need to add ...

                      You are most welcome.
                      well I think its a bug but not sure.
                      When bug comes, it seems to me it hangs. That seems like bug.

                      Oh I forgot to ask.
                      What is {8856f961-340a-11d0-a96b-00c04fd705a2} ?

                            You say that if made with button, then bug dont show, but if you minimize and maxi window again, bug comes back?

                                Have you tried with Qt 5.5 ?
                                Maybe QAxWidget has bug in 5.6

                                  Hello!

                                  I faced a similar problem, tried hacks with single QTimer and showEvent: timer was a solution, and showEvent -- wasn't. I also use Win10, but Qt5.5.1. Have you succeeded?
