Weird graphical issue during Big Octo fight due to wave position

[RecursiveVision]

This occurred while fighting the Big Octo northwest of Tingle Island. I started the fight heading east from Rock Spire Isle.

I think the waves were high when I Swift Sailed into it and didn't get a chance to lower. The Big Octo stayed level with KoRL but both KoRL and the Big Octo were clipping through the water on-and-off, and the whirlpool was not entirely visible. This made defeating it more challenging, though I did succeed as you can see.
