Rook visualization error

Anyone else has a visual problem with the rooks that makes them looks like minecraft omlets?

This was taken in Live Chess. The whole session looks like this and reloading doesn't help. 

Looks like quite an anomaly.  What browser/version are you using, and have you tried clearing your cache?

I use Opera. I'll try clearing the cahche when I'm next to that computer again.

Thanks. 

 You'd think it's fine, but only when you play you realize how bothering it is. You're used to see patterns and evaluate positions with the rooks as they usualy appear. I kept missing moves with those rooks.

I updated to the new browser version (12.0) and it is fixed.

Thanks. 

Maybe the knight was halucinating about the wonderful meal that was about to come about...  He was hungry, you cant blame him.
