Where two gmasks intersect the gradients dont add/subtract smoothly. Nothing crazy, vanilla draw two masks and pull the grads out, performed millions of times before. Happens only in Action though, copy/paste into a gmasktracer and its the usual expected result. New bug???

Isn’t this because, in Action, those are effectively punching holes through a viewport and are effectively polygons, which means, they are geometry, which means, you can’t have transparent geometry?
