Created attachment 18741 [details] Repro file Originally reported against SumatraPDF: https://github.com/sumatrapdfreader/sumatrapdf/issues/1167 I verified it still happens in 1.16 On page 4 and 5, some parts are placed differently than e.g. Chrome (i.e. Foxit) or pdf.js
This looks like a tiling pattern is not being correctly tiled. The papyrus pattern background is only drawn once, and not stepped. The Matrix and XStep/YStep values and transform used during rendering are pretty extreme, so it may be related to precision issues or a forgotten transform somewhere. The pattern dictionary for page 4 (object 47) has these entries: /BBox [ 0 0 1625600 1625600 ] /XStep 1625600 /YStep 1625600 /Matrix [ .00007559055 0 0 .00007559055 16.37504 168.7761 ] And this content stream: q 1625600 0 0 1625600 0 0 cm /Im8 Do Q
