If you have screen glitches on 4 player chess then you should see a question mark either on your bottom left or top right. Then hover over the question mark and you should see a bugh which says ''Report a Bug''. Click on it and you can tell moderators and staff what your problem is.

I just had a look at 4 player, and the screen does not stay stable. It glitches between a blank screen, and the 4 player board, and changes between these two states every second.
Not functional. / Not working.
