white box around text - Adobe Acrobat Pro DC
I've got some text layers 95% opacity with drop shadow applied on Illustrator. Those Ai files are linked into a Indesign doc, exported as PDF but when I view the artworks on Adobe Acrobat Pro DC (version attached) there is a white box around the text. This only happens on Adobe Acrobat. If I use Mac Preview it looks fine. I can only fix the issue if I make the text layer 100% opacity in Illustrator. This bug only happens when the doc is viewed on any zooms that are 100% or less. It looks fine on 125% or over (see files 'wrong'/'right' attached)...

Could you please share the workflow elaborately.
Please attach the source files too.

Something you might want to check—it may or may not solve your issue. I have long seen similar artifacts on PDFs exported from Illustrator and/or InDesign with transparency—at least since Acrobat 8. Sometimes they would appear as a thin white line around the transparent object, too. Usually they are just screen drawing issues that do not affect printing. Turning on Overprint Preview in Acrobat shows them as they will print (Print Production Tool > Output Preview > Simulate Overprinting).
