EFS-Web continues to ruin perfectly good PDF files

Well, today we e-filed a Rule 132 affidavit, and attached to it were several pages from a textbook. The PDF file was perfectly clear when we uploaded it and previewed it in EFS-Web. But after EFS-Web loaded it into IFW, the PDF file became nearly unreadable. Quoted below are small excerpts from the PDF file, before and after.

I hate to think what the chances are that the Examiner will have the patience to read and to consider closely the content of this PDF file.
