Just happened at one game, "sort of twice".
It may have been something like 10-6 moves on both sides, and then the pieces move as if "transforming" into a whole different game, still at the 4th move or so. I don't believe it was an earlier stage on the same game, but something different altogether.
Sort of twice because, once I resigned, it eventually returned to the "previous" game.
I'm using firefox (technically iceweasel, 31,2,0) on linux. With chrome/chromium, that never happened.
Just mentioning in case it may be useful, somehow...
