Fog of war glitch

This interesting glitch happened in one of my games. The board was blacked out, clicking on the pieces, would reveal additional squares.

It seemed like fog of war was activated haha.

Ha, that's pretty cool. Sorry about that; maybe some CSS or something failed to load? I'd ask how to duplicate it but I don't even know what to ask.

For a moment I thought they'd introduced fog of war to lichess.

Same same. I was momentarily excited. Had some fun games with several top players on that other site in the past.
