Hello everyone ! Robert, in fact I found exactly where the problem comes from:
Above my star object (so all my points in a geometry in a geode) I added an osg::Camera On this camera I have an event callback, and in this event callback I used to set the Camera viewport and graphics window to be the same as the master camera (except that: 1. I doesn't make sense with a CompositeViewer since we have 1 event traversal for possibly many View, and 2. Now I know this is pointless anyway since a sub camera will retrieve the parent camera viewport if it doesn't have its own (and I assume it's the same for the graphics context ?) ) Anyway, if I remove this event callback from that camera, everything is fine, if i keep it, I get this awfully long draw + GPU phases for at least one View when I have two of them on the same scene. Maybe you have an explanation for this ? But I just need to find a better implementation for handling those stars anyway.
