At 160x320 it renders fully as expected; at 159x318 I get only the first court in the upper-left, with no text or other bits. No error messages visible. Example command line: $ rsvg -w 160 -h 320 Badminton_court_legal_bounds.svg 160.png May need to file this in the upstream Gnome bug tracker: https://bugzilla.gnome.org Latest release of librsvg appears to be 2.34.0, so this (and many other rendering issues noted in our own bug tracker!) should be retested against that release as well as whatever we currently have in production. > Not sure where the bug is.
