Graphic bug with the credits

I don't know the origin of the problem, but there is a problem with the transitions in the credits.
Video footage.

I believe this is the viewport being set incorrectly. Could you try if it works as expected if you use a build without antil-aliasing and without 800px wide? If that works right, I know what I need to change.

Using a 400px build without anti-aliasing resulted in a very similar problem, but now, most of the “pictures” are still squished, but they also wrap-around vertically.

I was able to fix it by changing gfx_citro3d_set_viewport to this:

static void gfx_citro3d_set_viewport(int x, int y, int width, int height) {
    C3D_SetViewport(y * 2, x * 2, height * 2, width * 2);
}
