or wrap changing fill and stroke inside spaceCenterDrawBackgroundLineView spaceCenterDrawLineView notifications. A multiline view has a _fill and _stroke attribute you can temporarily overwrite. good luck

here’s a different approach using representations to cache the interpolated glyphs — this may help in terms of performance…

hello @bahman, representations are handled by defcon, the docs are here. glyph = CurrentGlyph() path = glyph.naked().getRepresentation("defconAppKit.NSBezierPath") cheers!
