> In Chrome, I notice that the very-wide Bismillah glyph is rendered with lower-grade antialiasing than the rest of the text
Chrome GPU rasterization seem has issue with big glyphs in general (I get the same effect with COLR fonts at bigger font sizes) and disabling GPU rasterization fixes the low res rendering, but I get the same clipping as Firefox so it seem like this is a DIrectWrite issue indeed.
