Some issue with the appearance of the board!!!!

Today while i was playing the tournament, the board became so dull that the squares cannot be seen. It looks like a skeleton board. I feel very uncomfortable with it. Is it a bug or I have to play with some settings?

Note: My android app works fine.

The same happens to me, it definitely seems to be a glitch.
I made a forum post about it as well.
Does it look like this to you?

Yes, almost like this.
But for me, the board also goes black and white.
