I've counted the pixels for different scaling factors, and the sizes of the glyphs are generally within 1px of each other (native vs. JFX). What seems to be happening is a combination of pixel snapping, and a different rasterizer (in this specific case, JFX seems to bias the inner edge, whereas Windows seems to bias the outer edge).

(top is JFX, bottom is native)
