Solo; just read thsi in the Vue manual:

Panoramic View
Real panoramic cameras are fixed to a handle that you have to hold when you take the shot. As it
takes the shot, the camera rotates around the handle, thus embracing any required angle of view.
Panoramic views can yield beautiful results.
This option is a numerical equivalent to the real panoramic camera. Here also, the camera is rotated
as the render engine makes progress. All-around panoramas can be achieved this way, but
beware: if the camera is not perfectly horizontal when you take the shot, the horizon will undulate.
This is not a numerical artifact: it happens also in the real world!
When you select this option, the panoramic
H Angle slider becomes available, letting
you decide on the horizontal angle swept by
the camera as it rotates.
This appear to be what happened to your VUE environments.
