The odd while loop there is used to simulate branching instructions with jump offsets.
The executable blocks without conditions are what concerns me since they are creating unreachable code
Here is how it's supposed to look:

And this game as well as Atelier Rorona, Totori, Ayesha, and Ar Tonelico 3 have the same bug where the game will eventually start looping forever at some random scene, usually with the camera going nuts:

EDIT: And yes the game does the exact same things on OpenGL, Vulkan, and DX12 with no visual differences as far as I can tell.

I'm unsure. I'll need a framecapture in the scene with the girl in it for transform reference if possible.
I have opened a new issue tracker for this https://github.com/RPCS3/rpcs3/issues/2218
The same scene with the black and white sky? That could take a while, usually the game doesn't get that far before breaking. However the scenes before it also have completely broken building geometry in the form of a thin pillar. I'll see what I can do. Do note that the game takes ~5 minutes to start each try (very slow loading)

For the record, just for the sake of keeping track of changes,
the messed up graphics are fixed as of today. This also applies to Atelier Ayesha although it needs a
hack in cellSave to go in game (and then still hangs in 0-3 seconds).
