Oh wow, that's the first time I've ever seen a bug like this.
I feel like we should report it to the developer of the Ren'py game engine itself.

I would appreciate it! Any idea what else I could try? It's like all the backgrounds and CGs are split up into 3 misaligned segments. :(
I never had any issues with Ren'py games before. This error occurred right from the start and also affects the gallery btw. The strange thing is that the thumbnails look fine, but opening an image results in the above bug, which is also present in-game.
I managed to fix it!! I had to disable Ren'Py's OpenGL support, which is done by holding down shift while starting the game. I was then able to force the game to use a different software renderer from the available options and now the backgrounds and CGs look as they should both in-game and in the gallery. I am SO relieved. Hopefully I can finally enjoy the game now, lol.
