Entire person mask is essentially unusable

Not sure when the change happened as I haven't used it in a while, but whenever I use it, the selection includes a border around the person as well. It also looks quite pixelated/blocky. And this is not related to my system in any way as it happens on every platform I've tested on, as well as on the web UI on multiple platforms. I've confirmed the behavior on multiple photos (across a wide variety of lighting scenarios) as well.
