Everytime you join game, the chat opens.
But when game finishes, the chat remains opened and it overlays join button for knockout.
Not critical issue, but can be little bit annoying in time, that you have alyways to minimize the chat before joining the game.
Every single game like this:
So my suggestion: Make the chat larger in lobby … in lobby, there is time for chatting, so players would feel more comfortable with larger chat. In game, the chat will remain as is now.
something like this, just for ilustration, size of arena images can be smaller for better scale-resolution handling …
++ maybe in lobby, if it will be some like this, there is no need for chat hide, nor ingame …
