      These days I upgrades the QGLWidget to the QOpenGLWidget in my program.
      The glReadPixels is not work, and it gets an error 1282 from the glGetError.
      I had set the format QGL::SampleBuffers at the constructor of the QOpenGLWidget.
      When I excludes the QGL::SampleBuffers from the format setting, it is work well as upgrade before.
