env is system Win10 ,osg 3.6.4, osgearth 2.10.0,GTX1660 TI

Why is there an error in the model texture display when this function is 
turn on?

 const int width( 800 ), height( 450 );
    const std::string version( "4.3" );
    osg::ref_ptr< osg::GraphicsContext::Traits > traits = new 
    traits->x = 20; traits->y = 30;
    traits->width = width; traits->height = height;
    traits->windowDecoration = true;
    traits->doubleBuffer = true;
    traits->glContextVersion = version;
    osg::ref_ptr< osg::GraphicsContext > gc = 
osg::GraphicsContext::createGraphicsContext( traits.get() );
    if( !gc.valid() )
        osg::notify( osg::FATAL ) << "Unable to create OpenGL v" << version 
<< " context." << std::endl;
        return( 1 );
