Just encountered this in Wispy Ruins. If you try to interact with this pillar, it asks you if you want to surf. If you do, this happens and you can surf around on the floor. Going onto water and back to land fixes it though.

Encountered this bug when I am about to fight Eli and Sharon for the first time on Route 1
I'm also having the same bug that DreamblitzX mentioned with entering east gearen
