While this is a valid logic for raster backends, it is a bad idea for PDF output. There we want to see all fine lines. My specific use case is generating a lasercutter drawing for an Epilog Zing laser with inkscape. There the hardware would raster anything thicker than 0.02mm, and cut 0.01mm or below. 1.12.3 skips lines below 0.036mm, 1.13.1 skips lines below 0.018mm -- which is still not enough to safely drive my lasercutter. Previously reported against inkscape: https://bugs.launchpad.net/inkscape/+bug/1174909 Also reported agains cairo upstream with a suggested fix: https://bugs.freedesktop.org/show_bug.cgi?id=77298 Check out the attached reproducer and fix. I'd suggest to circulate patched ubuntu packages, until upstream releases an official fix.
