A curious error - GraphicsWindowX11 shouldn't create a window without a context and I would expect the makeCurrent on the context to fail and be reported, what shouldn't happen is that the code to get to doing the draw traversal without a context being current. Could you try running single threaded via: osgviewer --window 0 0 800 600 cow.osg --SingleThreaded To see if that makes any difference. > Also get this: > osgviewer --window 0 0 800 600 cow.osg > Got an X11ErrorHandling call display=0x9514798 event=0xbfea5ca0 > XIO: fatal IO error 11 (Resource temporarily unavailable) on X server > ":0.0" > after 55 requests (55 known processed) with 0 events remaining. I believe this "Resource temporily unavailble" is the one I was getting. Running the same test above things are working for me now. Grrr.... perhaps my recent OS updates have improved things, or perhaps it's just lucky timings.
