Other user not visible on Facetime
Recently, whilst trying to use facetime on my Mid-2014 MBP Retina 13", I have been able to call other users however I cannot see there video feed- only the view of my own camera covering the whole facetime window.
A similar thing seems to happen when another user calls me- except the facetime window becomes smaller and sticks in the top right corner of the screen- there are no buttons visible and the only way to quit the facetime window is to Cmd+Q it.
I have tried to back track removing any programs that may have caused this but to no avail- the problem still persists.
Many thanks
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
