Fate/Extra

[Truner]

I've been trying to play this game on two of my devices, a GPD XD (running android) and a Windows PC, both running the latest version of PPSSPP (Gold in Android's case, proof of purchase available if required by the devs). In both cases, I've noticed the VN backgrounds to not function properly.
Using OpenGL on Android, the backgrounds work, but they are offset. So checking a door results in a VN Background that shows the action before it. If you check the second door on a floor, you see the BG of the first door. If you enter the rooftop, you see the BG when the camera changes on the third floor, etc.
On Windows, OpenGL produces the same results, Vulkan has black backgrounds with a white spot near the top of the screen and surprisingly, Direct3D11 shows the images properly. I was kinda hoping I'd be able to play through this on my GPD XD, it being the most comfortable and PSP-like solution, so I thought about dropping a message here to see if it's a potential easy fix or not.
