I'm busy with other work right now so can't look at the modified code right away. My best guess right now is that osgText and the StatsHandler are using GL2 shader paths that assume gl_ builtins are available, but with the aliasing enabled perhaps this is causing problem. Could you set the DIsplaySettings ShaderHint to GL3 to see if that helps i.e. To the main before the scene graph setup add: osg::DisplaySettings::instance()->setShaderHint(osg::DisplaySettings::SHADER_GL3); Robert. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
