    Description

      I noticed an incompatibility between Qt 6.5 and earlier version. My code does something like this:

      void MyWindow::event( QEvent* event ) override
      {
          if ( event->type() == QEvent::Show && size().isEmpty() )
              // setting some default size ...
      
      }
      

      The basic idea of this code is to set a default size when the application code did not assign something explicitly.

      With Qt 6.5 the following line has been added in qxcbwindow.cpp line 269:

      QPlatformWindow::setGeometry(rect);
      

      what happens before sending the Show event.

      In earlier Qt versions a window gets also initialized to same default size, but later.
