The OSG's rendering backend is both very dynamic (created on demand on each frame) and flexible (it can be a huge range of bin configurations, potentially different on each frame) and the threading and multiple graphics context rendering are all thrown into this mix. This makes reuse of data something you have to be very careful about, in your case you'd either need to create on each new frame or multi-buffer.
