Every time I skype with somebody the video is never stable, it flashes constantly with strange blue background. Secondly I don't see myself in the little rectangle at the corner, but just a zoomed part of it, although the person with whom I am speaking sees me well and has no problem with that.
I have a Dell XPS 13 (9350), i just upgraded to Ubuntu 16.04, before I had 15.10 and I had the same problem.
