    Description

      Many of our autotests have been lately failed in qWaitForWindowExposed()/Active() and this is beginning to be a big problem, since it slows down the CI. This is not macOS problem only, but it affects all platforms. Every platform has it's own interpretation of when a window is exposed. See: https://bugreports.qt.io/browse/QTBUG-53252

      At least the following tests are failing:
      tst_qdialog, tst_qmdisubwindow, tst_qmdiarea

      At the moment qWaitForWindowExposed() is implemented in terms of QWindow::isExposed() and QExposeEvent. However the desired behavior here might be slightly different: The expose event is sent just before the window becomes visible on screen (Qt needs to draw a frame then so we have something to display on screen), while qWaitForWindowExposed() probably wants to wait until after the window has become visible and is stable.
