How do I get rid of the line?

[benatfroemming]

I am using maplibre and have a geojson layer above, however, when I hover onto some countries using fill with opacity, at specific zooms, a line shows up crossing the country (is it a seam?). Anyway, anyone has any suggestions on how to fix this? Thanks!

Hard to say without seeing any code, but I would make sure the geojson you are using is valid.
Try simplifying it and see if you still see the issue...

It's the Natural earth 10 m geojson, I used the 50 m and seems to not have that issue. Thanks for the help!
