    XMLWordPrintable

Details

    • Windows

    Description

      In an MDI application with an MDI area. When an MDI subwindow that contains OpenGL (QOpenGLWidget or QWebEngineView) is added, the application window briefly gets hidden and shown again, i.e., it "blinks".

      Attached example reproduces it.
      In the document Note does talks something similar
      https://doc.qt.io/qt-6/qopenglwidget.html#resource-initialization-and-cleanup

      If this is something not going to be fixed, then can there be any workaround?
