Tekken 8 Steam focus issue bbox 14.0

[zerotwoeight]

been having some issues with Tekken 8, and it seems Soul Calibur 6 as well. wondering if anyone else can test for me. in big box, the app never seems to switch focus. it just hangs on a black screen, until i alt-tab it over to the game. at first i thought it was a steam issue, but i think it might be a namco games issue. tested streetfighter 4/6 and they work just fine. doing some digging i thought it might have been my thirdscreen plugin (ThirdScreen-v6.0.2) but that's uninstalled and not it. I'm using bigbox on my cab and it just kills me every time i have to fish out a keyboard or mouse to fix. any help would be apricated. thanks guys. i'm going to test on a different machine, as well as do a clean install to see if maybe it was just this instance that was causing me the issues.
