    Description

      When you use QSG_RENDER_LOOP = basic (by default), and when you create a new parent window using QML, all windows redraws.

      I attached QML code and video to reproduce. 

      This does not happen if you use threaded rendering, but Qt 5.12 with MacOS 10.14 not work with threaded rendering (https://bugreports.qt.io/browse/QTBUG-75037)

      Edit: 

      If use MacOS SDK 10.13, all works fine.
