Hi nervenbuendel,
Sorry it's not running for you. I've just reinstalled the latest version on Ubuntu and I'm not seeing this. Can you run the game from the terminal with the parameter -console:
/home/stephan/.config/itch/apps/smith-and-winston/SmithAndWinston -console
this should make the app print a lot more information. If you could paste the output here or email me at dazza@executionunit.com whichever is easiest for you.
Thanks for your help.
