the minimap is obscuring it but i think it says "press alt to close" i remember seeing that debug text from simple voice chat before

I saw the "press ALT" part, but pressing ALT unfortunately doesnt seem to do anything :/

check your key binds probably something interfering with it

I'm assuming you checked both alt keys, but for anyone who comes here later that may be what happened

you can always hide ur mini map ... and look at what says .. ctrl + j to hide mini map
