QGraphicsView fails to properly set QOpenGLContex::defaultFramebufferObject

    Description

      I'm using QGraphicsView with QOpenGLWidget as viewport. When using QOpenGLFramebufferObject::release() within QGraphicsItem::paint() the current OpenGL framebuffer is set to the system's default and not to the QOpenGLWidget's framebuffer.

      QOpenGLWidgetPrivate::invokeUserPaint() sets a flag on QOpenGLContext before calling virtual QOpenGLWidget::paintGL(). QOpenGLContext::defaultFramebufferObject() then returns the QOpenGLWidget's framebuffer while in paintGL().

      This initialization step seems to be missing when using QOpenGLWidget as viewport for QGraphicsView.
