    Description

      I understand that desktop applications might not be top priority but this bug fix is overdue. 

      It seems like the OpenGL context is being damaged and/or destroyed when a QDockWidget is floating. Completely disabling the paint/update of the QOpenGLWidget.

      Please, see the modified cube example provided.
