Which version of the OSG are you using?

I am actually experiencing somewhat the same thing you are experiencing.
All of our text is rendered on a different layer, which is usually the highest render bin, so it can be viewed above all other shapes. Each layer first clears the depth buffer before each shape for that layer is rendered. The layer here consists of a render bin that all the shapes are dumped to. What I am seeing is the text starts rendering above all others, but then, after several render passes, the text start rendering as if depth testing is turned on. Shapes from lower layers seem to occlude the text shape. This is strange behavior. I would expect one or the other.
I have not looked into the code quite yet, since I wanted to see if anyone else has experience the same problem. I will post my findings later.

Hi Robert,
I do see the difference when commenting out the depth test setting in your example, the surface directly beneath the text partly occludes it with depth test turned on, so it does work to some extent. But when viewing your text on the earth surface "edge-on", I can observe that the earth is occluding your text. Is there some sort of culling going on?
Can you see the text behind the horizon? I guess you should be able to do that if depth test is switched off. Or perhaps there's some obvious reason I can't see right now, due to lack of sleep or something...
