I extracted with bisnet-fp masks. Open the manual tool to check. If the mask is off, I can fill it in (or erase). But in some cases when I zoom in or out, the mask shifts. Example, I click on magnify and erase some of the mask that picked up hair or background, hit magnify again to zoom back out, and now some of the face is missing mask. And vice versa.
If it's a bug, which should I rely on, regular view or magnified?
