Fran- on my phone, things look normal if I hold the phone vertically. If I hold it in landscape, the avatars are a bit distorted and take the whole screen, which is fine. I tried to add a picture so you can see it.
On the computer, the avatar had been sort of like the picture for the last few days, which was strange. Some were more distorted than others.
However, right now, looking at the computer, everything is normal.
