Could you be more specific? What was the name of the card game that caused the problem for you? I have the same issues with the touchscreen, the screen auto brightness, but I also have another issue that I haven't seen mentioned yet. When I put my XPS 12 in sleep mode it won't stay, it comes back on instantly. My only options are to shutdown or hibernate which isn't a big deal since it's 4 seconds to resume from hibernate and 8 seconds from shutdown. I don't recall installing any card game from microsoft but if you know the name of the card game I can see if it's there to uninstall.
Thanks
