We have issues with that in our rasterizer too, which I do not know
how to solve short of oversampling. Perhaps, Raph or David have some
thoughts on how to deal with pixels where contours intersect and
coverage is calculated wrongly. Whoever let intersections into
variations fonts should also have some ideas on how to rasterize those
unless the decision was made hastily.

I still doubt that variation fonts have legs. They were dead in the
water for 20 years are still too complex to survive, IMHO.
