Package: diffpdf Version: 2.1.3-2 Consider the two files mwe1.pdf and mwe2.pdf in the attachment (obtained from the question and answer on https://tex.stackexchange.com/questions/587968 https://tex.stackexchange.com/questions/587968 ). In mwe1.pdf, the upper occurrence of “c3:b” is printed twice at the same position, which results in a visibly bolder appearance in, e.g., evince, okular or qpdfview at 100% magnification. In mwe2.pdf, the upper occurrence of “c3:b” is printed once as usual. These files visibly differ. Sometimes you do wish to catch these small variations. However, diffpdf says, “The PDFs appear to be the same” regardless of what you compare: words, characters, or appearance. Could you please make diffpdf actually notice the difference? Thanks for the bugfix in advance, Peter
