I am sorry, but i could get the problem.
Would you please elaborate what is the problem you are facing with Adobe Reader DC?
I have two Versions, the Adobe Acrobat READER DC and the Adobe Acrobat PRO DC on my PC. The Scrolling doesn’t work anymore in the Acrobat Pro since the last update. This only happens, if there is more than one document opened. I have marked the Areas on Screen where it scrolls (right Picture). In the Center of the Screen nothing will happen.
Can I reset the engine or downgrade to the last Version?
Sorry for the inconvenience caused to you.

I am not able to reproduce the behavior you are mentioned above.
I have solved my Problem with reinstalling the graphic Driver. Thank you!
