Looks about the same
Damn :/ Not sure how to proceed with that. I downloaded Ubuntu and Virtualbox and I'll try setting up a Linux environment on my older machine so that I can test it on an environment similar to yours. I could also try installing TuxedoOS. I'm sorry you encountered these issues, they never occurred to me when testing or developing the game and I don't know what could cause them.
I'll try to get to the bottom of this.
