I'm unsure if this a problem with the game or Linux but when I launch the game it says the the game is not responding and offers options to wait or to close the program

If I press wait the game launches without a hitch but it is still a minor annoyance

This isn't related but once the game stopped recognizing the joysticks and analog triggers of the controller

Relaunching fixed the issue and it never happened again but maybe you should be aware of it
