Saw another user's username in the top right?

aranym@lemmy.world to Lemmy.World Announcements@lemmy.world – 17 points –

Only time it's happened, I had to refresh to get it to go away. I checked and the username is real, they joined 3 days ago.

Is this a common issue? Any security risk?

Sometimes the lemmy frontend also changes the post that you're reading atm, but as far as we know it's not a security risk at the moment. It's just shown, you can't act as that user or post.

tl;dl: bug

Oh wow. I've heard of comments ending up on the wrong thread, but that sounds bad.

edit: Come to think of it, I bet that has to do with why the vote counts vary so wildly sometimes (I just "upvoted" this post from 889 to 4)
