      Tested in the Qt "qopenglwidget" example and another application:

      void GLWidget::initializeGL()
      {
      initializeOpenGLFunctions();
      m_texture = new QOpenGLTexture(QImage(":/qt.png"));
      m_texture->setLevelofDetailBias(-0.65f); //<== added this in line ~223

      Without the last line the application works fine.
