Is it malware, user error, or a bug? Opinions are all over the map.

User kar0786 on the reported the problem on March 22:

"My boyfriend and I have both recently experienced this problem several times--when one of us is calling the other , an old picture freezes on our screen, while the person receiving the call only sees a black screen," she writes. "It's kind of creepy, because it brought up photos of both of us at work, where I have used FaceTime a few times but he never has."

User mattyohe at , where they presumably know what they're talking about, confirms the problem:

"While I can't consistently reproduce this issue, I was able to get FaceTime to show up with some random image of myself in the preview of my FaceTime call. Basically: 1. Open the camera app and flip the camera to yourself. 2. Close the camera app, and call yourself on your Mac's FaceTime app. 3. The image that showed up was of me frozen, from just a few moments prior when I flipped the camera around."
