It's not really a texture image at all. The game's object shader is just replacing the usual texture color with a snowy one where the pixel's normal vector is close enough to pointing up (as that's where the "snow" comes from).
Problem is, it's not blending between the two colors at all, so pixels either get full snow color or full regular texture color. This could be fixed in a couple of lines of high-level shader code, but maybe the console GPUs couldn't handle the arithmetic.
Since the aliasing is being generated by the pixel shader, the only things that could reliably counter it are fullscreen supersampling or FXAA (or some other postprocesing AA). I'm using FXAA myself, so this doesn't really bother me.
