Blurred PDFs after Opening from SAP

Hello,

we have a problem: with the MS Edge in the IE-mode with the Acrobat Reader DC Plugin the PDFs are blurred after exporting from SAP. With th Acrobat Reader 2017 this error doesn´t appear. But the problem is that the Acrobat Reader 2017 has no longer support. Does anybody has a solution for this problem?

Thanks a lot.
