I first noticed it ages ago but forgot to report it.
Bijon Hello, thanks for your feedback. In fact, it's not a bug, it's designed to act like that to avoid dizziness.
Really wish Skybox would allow users to choose the left or right image for their dominant eye in Skype monoscopic scenarios. This could help avoid awkward experiences when switching between stereoscopic and monoscopic images.
Ted Received! I will pass your request to our dev team.
