Hi Dyne, I'm not sure where would be best to put this as its just a small bug I've been having for a good while so ill put it here. I'm on the PC build of the game on the patreon version, and often when I turn to fullscreen mode my screen will flicker the back of the art with a black screen. It's a little hard to describe, it happens for me occasionally at all times but gets a lot worse when it changes to an art CG flickering more consistantly, but only in fullscreen mode.
Anyway sorry for the bulk text, I can get in touch with a video if wanted.
I'll finish by saying it definitely doesn't impact how much I love this game and the world you've built!
