it's not a priority bug, the raster effects are off by 1 line.

fixing it breaks other games relying on the same logic tho.

Are you sure it's only about the line that's off and not a priority problem? The stars from the background are shown on top of the planet, where they shouldn't be.

IIRC when I applied a manual hack to the raster effects those stars weren't there, although it's been a while since I checked
