Created attachment 67869 [details] pdf with wavy lines In the attached pdf file, generated from inkscape, there are wavy lines in one section that do not render correctly in evince. I have tried different versions of both inkscape and evince, and have generated the pdf as pdf 1.4 and 1.5 from inkscape—all with the same result. Other pdf viewers, including xpdf and acroread, display the pdf correctly. I am attaching the pdf, and will add screenshots of a correct rendering of the wavy lines in xpdf and the incorrect rendering in evince. The latest version of evince I have tested this with is 3.4.0 using poppler/cairo 0.18.4.

The trouble seems to be that pixman refuses to render the image because its internal coordinate representation would overflow. The wavy lines are rendered into an 3007x518 pixel temporary surface, which is then rendered to the screen. This is done using a matrix of (0.008, 0, 0, 0.008, X0, Y0) where X0 and Y0 are the offsets. It may even be possible to get things to work sometimes, if you choose certain offsets instead of the ones given (ie. you center the origin of the pattern inside the target area). The 0.008 means that the transformation has the value "2^15/0.008" ie. 4096000. This multiplied with the extends of the destination surface (or clip region really) overflows the 32bit integer representation. Because of this pixman refuses to proceed.
