Hi Brad, I don't have time right now to dive into this topic, but my guess is that the default bounding box for the text is small enough for small feature culling to cull it's parent so that the text itself never gets traversed. Perhaps making the bounding volume invalid until it's been traversed would be one thing to do, so for the first frame it's not culled. You'd only want to do this in the case of screen scaled text.
