Do you create your own osg::Camera and assign it to the viewer? If so it's likely that you haven't set up the OpenGL settings to properly render your scene. A bug in OSG-3.0.x and before meant that the Camera StateSet was overridden by the rendering backend and defaults that work well for most OSG apps installed in it's place. The reason this is a bug is that it discards the settings your applicaion would have set. With OSG exmples like osgtext they don't suffer from this problem with lack of useful OpenGL default settings as they don't assign their own osg::Camera, instead they use the View(er)'s Camera, and osg::View automatically calls StateSet::setGlobalDefaults() for you. I have written about this a number of times now, before and after the OSG-3.2 release, go check the archives. the osgtext example will crash, even tough the font was found.
