I don't know if it will ever be fixed. The game was released on the 29th of September, and so far no patches have been released at all, at least on GOG, so there's a good chance that this is yet another developer who doesn't care about its customers and will indefinitely leave the game in a broken state. I hope they won't, but at this point I'm not holding my breath.
One option you have, and it is a very messed up one, indeed, is to take apart the gamepad and remove the part that makes the gamepad vibrate. There are tutorials on youtube, but embark upon this endeavor at your own risk.
