Hi Tiziano, osgviewerQt is working fine for me. I'm using Kubuntu 11.11 and NVidia drivers. From glxinfo:
OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 560 Ti/PCI/SSE2 OpenGL version string: 4.1.0 NVIDIA 280.13 OpenGL shading language version string: 4.10 NVIDIA via Cg compiler >From the look of the stack traces the problems you are seeing are driver related. The example runs in mulit-threaded, perhaps this is what introducing problem with the drivers. Try running osgviewerQt --SingleThreaded Robert. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
