Hi J.P, I've tried out your example and found that with paged databases and your supplied model everything works fine for the first viewer then on the subsequent viewer I get:
Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..) Warning: detected OpenGL error 'out of memory' at after RenderBin::draw(..) Warning: detected OpenGL error 'out of memory' at after RenderBin::draw(..) For none paged databases, even ones with texturing I'm not getting any errors though, for any of the viewer runs. I really don't know what this means if anything, perhaps just a coincidence. Curiously your database uses straight osg::Geometry meshes for geometry, while the ones of mine were built with osgTerrain::TerrainTile. Your database will be only loading the topmost tile so the DatabasePager won't actually be even playing a part, so I doubt this is part of the equation. While I can't see a particular pattern emerging, I can at least reproduce the issue. I'll try and remove the multi-view element to the equation as I wouldn't have thought use of CompositeViewer will be a particular problem for VBO/Texture object usage. Robert.
