I am trying to make a globe type map with an orthogonal projection (made using a custom projection with the "origin" set to 20,0). The issue is polygons which meet the edge of projection are clipped by it. From some angles this is not such an issue but here Russia has been partially inverted.

My workaround would be to open a PDF in Adobe Illustrator and alter the vector paths on that, not ideal. Is there anyway to do this in QGIS?
