I think the right move would be to ask for clarification from the floor admins regarding what your responsibility is in this kind of situation. The onus is on the opponent to cover their cards. If you're not doing something extraordinary and still seeing their cards, then it is the opponent's problem and not yours. Once the floor is aware of what is happening and allows it to continue, there's no reason to do anything else differently.
Had the question been worded differently, such as if you hadn't warned the other player first about the issue, then it becomes a more complicated situation where you may be getting an unfair advantage over the rest of the table without everyone being aware, which to me is fraudulent as it isn't just the card shower that is affected but instead the entire table. The game is no longer pure poker. Ethically and legally, the right move is to notify the table about what is happening so that everyone is informed and can make an informed choice regarding whether to continue playing or not.
