The gradient 5 and gradient 28 has a line.

[handy]

--gradient-5:conic-gradient(from -270deg at 75% 110%,#f0f,#fffaf0);
--gradient-28:conic-gradient(from -90deg at 50% 105%,#fff,orchid);

I fixed it below:

--gradient-5:conic-gradient(from -270deg at 74% 110%,#f0f,#fffaf0);
--gradient-28:conic-gradient(from -90deg at 49% 105%,#fff,orchid);

Is this issue still relevant? I don't see any lines in the gradients currently on ff or chrome. What browser are the screenshots from?

12 in your example also has a line.
it's odd/fishy that the lines are only on conics and seem random.
can you create a link that reproduces the issue for us to preview? look like you've removed the overflow styles in your screenshot and made swatches from the list 🙂

closing for now, feel free to reopen if/when you find more or have clear reproduction steps
