Poker Stars, Small Star Above Avatar?

[MeanGreenTT]

Anyone ever seen this? I was searching for a player and when I opened up the table, I noticed one of the players had a small white star at the top center of the ring around the avatar.

It wasn't part of the avatar, defintely part of the Stars software, or at least appeared that way to me.

Sorry if this is ancient, common knowledge. Thanks in advance.
