    Description

      Story

      I want to use grab() system on custom QOpenGLWidget which mix OpenGL / QPainter.

      Currently, if I try to grab a widget which contains my QOpenGLWidget. The OpenGL rendering is called (paintGL()) but not paintEvent() as expected.
      See MyGrab.png result.

      The quick demo to reproduce bug is attached.
