Comment 7 for bug 1595139

If the pixel alignment was wrong you would likely see asymmetry in the rest of the icon too, but you don't. So it just looks like it's been cropped on the right.

That said, we've had a few problems with Unity8 being blurry in parts by failing to pixel-align textures (and text). So there's plenty of precedent for that mistake and I don't think we've resolved it all yet.
