Bug?

I was playing a daily game, do I decided to review the moves from the game, trying to figure out why I just blundered my queen, as it is still ongoing, but when I did so, I suddenly got the following chessboard, it is still ongoing in the daily game, as when I go back to the game, I get the same wierd chessboard, and Im wondering this is just a beta glitch or something else. Thank you.

The board Im currently using should look like 8-bit pieces with the blue chessboard.

It occasionally changes into the standard green board for me just before Chess.com crashes.

There's a setting in variants (most of them) to have a ghost board.
