Hi Moji, The code looks OK, so I'd suspect an OpenGL driver error.
Could you try OSG-2.8.1 or OSG-2.9.x/svn/trunk as this has a fix in Drawable::compileGLObjects() for the compilation of vertex arrays, this fix affected ATI drivers that couldn't cope with putting VBO's inside a display list. There is a chance that this might affect intel drivers as well. Robert.
