Hi Endre, Just to be clear, do you have your app running across all displays right now? Is it just the subloading that isn't working?
W.r.t subloading, this the unknown variable that makes it difficult to comment on. The best I can say is that osg::Texture* maintains a seperate OpenGL texture object for each graphics context. Have a look at the Texture*.cpp classes to see how these texture objects are managed. Robert.
