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.
Please see the following image. I started to use vertical taskbar since my monitors are so wide it makes more sense. I enabled the icons to display with the click and it seems that the click is getting cut off on the top and bottom.
Interesting! Could you attach a copy of the info from the Settings > Troubleshooting tab? I'll need to setup a test system here with the same configuration and 5 rows of tray icons
