Game Mechanics: Swimming issues

[Padlock]

I'm not entirely certain if it is a bug or not, but I've noticed when swimming to different isles in OOT or across lake rathe, whenever i minimize during the swim, i will be pushed down a rather far way underneath the surface.

I minimize so i might research while swimming, but with this possible bug it makes it impossible.

Is this a bug? or was this intended to prevent people from minimizing and afking?
