Hello hseiken!
I really appreciate your feedback, and I would like to see if I can resolve your issue. To do that I need to know if the game runs ok on the Fujitsu u820 in mode 1 and 2 (the two filter modes). Does it only malfunction in mode 3? If that is the case I might be able to fix the issue.
Also, if it's possible I'd appreciate if you could send a screenshot of what is happening to contact@styrbjornandersson.com.
Thank you!
