I have found that when a PNG image's row width does not correspond to a whole number of bytes, the low-order bits of the last byte in each uncompressed row can fluctuate between pdflatex runs, at least when libpng can perform SIMD-assisted decompression,
Just two questions, which came to my mind just after reading the report: 1. Could it be an issue in libpng* too?2. How did you learn the issue? You did notice that fltk* does FTBR and then found the root cause?
