Sometimes, I leave a table and quickly sit down in a better seat. When I do this, the HUD stats for me stick to the original seat. Even worse is that if a player sits in my old seat, both stats display in the same HUD window - my stats display all the time, but right after each hand, the other players stats briefly display instead and then it immediately switches back to my stats.
Note: I am on Wine, but I doubt it matters for this one.
