text not showing consistently at different zoom levels

We have been using Microsoft Aptos 11pt font in Word for our corporate documents, however, there have been some issues when converting the documents to Acrobat. I'm attaching 2 screenshots of the same thing at different magnifications. 

         Aptos 11pt font - Acrobat magnification 75%                                               Aptos 11pt font - Acrobat magnification 110%

Is there any way to fix this issue?? I've used the High Quality Print in the Acrobat print driver (this seemed to work for a while); I've embedded the fonts in Word but those things aren't helping any more and I need a solution. Also, 11pt font no matter the type size displays as 10.98pt in Acrobat but I doube if there any fix for that issue. Please help!
