Gwent graphic issue after winter update

Hello there! Gwent used to work wflawlessly for me. But since last update, graphics during the game are only red-green-yellow. Menus and everything else is fine. Anybody else have this? Any suggestions?

I have problem with GOG Gwent. “Runtime error at 53:566, floating point division by zero” Does it work for anyone?
I am running ubuntu mate 18.04, Linux 4.15.0-30-generic, nvidia 396.45.
