      Qt: Qt 5.9.3

      HW: Tested with NVidia Geforce GTX 1050. (Reported to occur in other Geforce GTX and Quadro P4000 cards as well.)

    Description

      Summary

      When a QOpenGLWidget is added to the screen and becomes hidden (either by QOpenGLWidget::hide() or or switching tabs), application GUI stops refreshing/repainting. 
      The application itself stays responsive but nothing is reflected to the GUI.

       

      Steps to reproduce

      1) QOpenGLWidget is shown inside [Tab 1]. Typed in "1111" into lineEdit.

      2) Switch to [Tab 2].
      QOpenGLWidget disappears and GUI freezes.
      Type in "2222" but not appears in screen.

      3) Resize the application size. Repaint is broken.

      4) Move back to [Tab 1].
      "2222" is appended in lineEdit. GUI is repainted and works fine again.

       

      *Please note that this example is tested on NVidia GTX 1050 with the latest drivers as of June 14th 2018.
