I'm not sure this is really the case with your scene, but I usually have similar problems when my scene scale is not optimized for my character. The best scene scale for V4 (and most human figures) is "medium". You can change the scale in Scene properties (Interface tab).

Also when the camera is clear but is not showing things properly, the problem could be that the distance to near plane is too large. (That is set in the camera's general properties)
