I have found out the env. OSG_SCREEN_DISTANCE is not set. The osg::DisplaySettings uses the value 0.5 for default distance which is used to calculate first parameter of camera.setProjectionMatrixAsPerspective(). This leads to an angle nearly 180 degrees for this parameter. After setting env. OSG_SCREEN_DISTANCE all examples work fine now. I'm wondering it seams to be nobody has this problem like me. Thank for your tip Paul but I didn't see anything strange after setting OSG_NOTIFY_LEVEL=DEBUG.
