It appears to be a display bug on your end. Here is what I see on that exact same game.
Did you get that screenshot from the game after it completed, while in live? The local client may not be accurately reflecting the actual times that the server logs.
Im playing a lot of bullet chess, but one thing that annoys me is that the opponents time often does not move which results in me loosing on time. Even if I count the seconds each of us use, it is about equal, but server does not count opponents seconds. With the new layout it was more obvious. Take a look at pic below and #18, #19 and #20. Me as black.
My web connection is tip top 30/30Mb fiber down and up.
What is the reason for this?
