Thanks for reporting!

I've tried to reproduce, and some readers seem to have this problem:

• Adobe Reader
• ImageMagick
• Ghostscript

Some other don't:

• Evince
• Foxit
• Firefox
• Chrome
• Edge

As this problem is not visible in all readers and not visible in PNGs generated by Cairo, I suppose that there's a bug in either these readers and/or in Cairo, and a "strange" use of the drawing primitives of Cairo in WeasyPrint. We can try to find and change this "strange" use to fix the problem.
