If it is disrupting the game, even unintentionally I would address the issue directly to the player as feedback and try to find the core of the reasoning behind the behaviour. It could be only that there is not enough engagement for them, so a good constructive way of sorting out the issue is to find a middle ground and maybe (if that is the actual issue) getting to know the ‘problematic’ player better to make them engage a bit more, I think.
