I think you are a little confused by what is a context and what is a shared context. You description implies that you have two graphics context, the second graphics context sharing OpenGL objects with the first context (this is what a shared context means), but is still a separate graphics context. It could be that there is an issue with the viewer setup, but equally is could be an issue in the OpenGL driver with sharing GL objects between contexts. Personally I would avoid sharing contexts historically has been be problematic with some drivers, and brings up limitations in the way that you can use the OSG i.e. you can't use it multi-threaded and you have to be careful about cleanup. The OSG can handle multiple contexts just fine, just don't set the sharedContext info when setting up your new context. Alternatively just share the same graphics context with both view's viewports on the same window - this approach will lead to the best performance.
