Animated or moving avatars

[Pepper]

Recently I've found myself having to scroll down while reading posts by users who have animated avatars. It's the strangest thing, but the movement of the image triggers vertigo for me. I've suffered with vertigo for the past 11 years, and often find myself having to look away from the television screen as well, particularly if there is a scene shot from a moving vehicle of any kind. I'm wondering if anyone else has this happen to them?
