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.
Thanks! Would you be able to post a full size screenshot of the Spotify window? We should be able to add an exception for Spotify to put the TitleBar Buttons at the correct offset, but unfortunately we don't have access to Spotify here in Canada
