I recently upgraded to MacOS Catalina. My refine edges seemed to start actingwonky after that.
When I choose to refine, the red mask shows up as expected. When I draw along the edges, all seems okay until the app finishes. At that point, the mask disappears and the marching and are completely gone.
If I click Apply anyway (without seeing the results), the marching ants reappear and show where refinement took place, but I have to hit refine again, in order to do more work. Also, the previews only work while the mask is visible.
Is anyone else experiencing this? I've been using AffinityPhotofor years and I can work around this glitch but it really slows me down. Any help would be much appreciated.
