Acrobat Pro DC: Problems with Scaling on Multiple Monitors/Windows 10

I have a problem with scaling of Acrobat DC UI, as detailed in the screenshots above (MS Word is positioned behind Acrobat windows for scale).

I have a Lenovo P50 with a 15' 3840x2160 high dpi screen (200% scaling); and a secondary 21' 1920x1080 monitor (100% scaling). I am running the latest version of Windows 10 with the latest graphics drivers available for my machine.

Acrobat DC looks fine on high-dpi screen. However, the interface becomes extremely large when the window is dragged to the secondary screen. Acrobat does not correctly resize the interface to 100%. As you can see, that impacts even the top title bar. Disabling scaling in Acrobat options does not fix the problem. The UI is then somewhat smaller, but still too large to be usable on the secondary display. However, everything becomes too small and unusable on the high-dpi display.

The only workaround that has worked so far is using the external manifest file:

Adobe App Scaling on High DPI Displays (FIX) | Dan Antonielli

However, this has significant drawbacks. The UI becomes somewhat blurry on high dpi display. Furthermore, the cursors on high dpi display become extremely small.

Is there another fix for this? Is the development team aware of this serious and critical bug? Will this be fixed in the next release of CC?
