I'm hoping I'll have more luck with this question regarding Affinity Photo.
Has anyone tried refining a selection after you've added a B&W layer to your photo? Looks like the red overlay becomes B&W too and to my eyes it's hard to tell where the mask begins and ends.
I try to disable the B&W layer, but then the mask disappears. I have to exit refine selection and click again on Refine on the top toolbar and then I get my red overlay back.
To the developers -
1. Was this the intended behaviour - at least the part where overlay also becomes B&W?
2. Are you able to recreate the disappearing overlay issue when you switch off the B&W layer? This surely must be a bug.
