Tested on multiple computers, it seems that when someone calls you into a video chat on messages (AIM) and there's multiple people in the call, it shows only the person who started it and their video looks as if you were looking into a curved mirror with the whole thing stretched out. With 1 person the call works fine, and if you initial the call it works fine. However when someone else calls you and there's more then 1 person, the problem appears. (AIM) I notified Applecare and they had no record of this. I tried multiple things like a call in safe mode to rule out extensions causing the issue, reset PRAM, removed messages folder in library and various other things. The problem is also on 2 different computers each running 10.8. Two different networks as well, one wireless the other wired. Not sure if this is a problem with everyone running 10.8, but it would be nice if people would comment on the issue and try to replicate the problem so Apple can release a fix. To replicate: - Open messages and login with your AIM account (not tested on any others.) - Have someone call another person in a video chat, then call you. If you have the same issue or not post here and let me know.
