If you downloaded DisplayFusion 12.0 and are having issues with languages please re-download and re-install. We have repacked the release as 12.0c with the languages fixed.
There isn't currently a function or scripting function for just blindly disabling the Monitor Fading feature, but I've added this to four feature request list.
Just wanted to follow-up and let you know that we've implemented monitor fading functions in the latest beta version of DisplayFusion. You can download the latest beta version from the link below:
