I’ve never heard of LightBurn. I presume you’re talking about the laser cutter software? If so, not knowing what it’s actually doing, I presume it’s just cutting along the stroke, rather than trying to do, I dunno, cross-hatch a fill or something? This case is specifically about fill, as I said, so if it’s just a matter of stroke then it’s quite correct in what it’s doing. If it actually is treating it as fill and getting it wrong, then that’s a bug that should be fixed and I have no patience with their implementation because it’s obviously wrong (as in: you’ll come across SVG like this all the time, there’s absolutely nothing anomalous about it).
