More examples of Expand Stroke not working as expected

[GarryP]

Windows 10 Home 1909, Designer 1.8.3.641 (and 1.8.4.650 beta).

Expanding the Stroke of a simple line gives unexpected results when performed repeatedly.
See video (Designer beta recorded) for two examples, one straight and one curved (AFDESIGN file also included).
I know this is a known problem, just thought I’d give some more examples which may help shed some light onto what could be happening.

Hi GarryP,

I'll pass this onto development to be investigated. Thanks for letting us know.

I am following the Expand Stroke improvements vimeo video but i can't get the stroke to be black in colour even though the setting is black as you can see. Any ideas why this is happening?

 

I can make the stroke translucent, but not change the colour

Welcome to the Serif Affinity Forums, @T-BONE.

The Appearance panel in your screenshot shows a black stroke and a red fill. When you ‘expand’ a stroke you end up with a filled shape that mimics the original stroke, and since the shape in your example has a fill but no stroke it stands to reason that it looks red: if you apply a stroke with a non-zero width, you should find that the stroke is black.

The two red objects have FX applied. If the FX is a red Colour Overlay then that will cover the fill and stroke, which would explain the black stroke not being visible. What FX is being used?
