hi,
when calling
view->show();
before setting
...->setFixedSize...
then the app Window is not created correctly as the top window bar is missing or respectively out ouf screen (feat. maximize, minimize, close).
OTOH, when calling view->show(); as the last, all is fine.

// show the view
//view->show(); // faulty
view->setFixedSize(800,600);
scene->setSceneRect(0,0,800,600);
view->show(); // correct
