Hello there!!
On the Antarctic Coast somewhat near Matienzo Base, as you zoom in, what was previously shown as open ocean is then rendered as "earth" instead of water. In short, the "earth" type is inconsistent between zoom levels in this area.
I became aware of this bug while developing a citizen science app of orcas using the Protomaps API where it's necessary to be able to distinguish between land and sea in these areas. I was able to reproduce the bug from within the Protomaps demo tile bucket. I screenshotted this demo bucket instead for this issue since it might be more informative.
After more research, I think it's due to using Natural Earth at further out zooms and OSM at closer ones.

At farther out zooms, Antarctica land has more water around this area:
As you zoom in closer, a huge body of land comes in:
