I noticed this with Tango: default cover is a svg, sized 96*96px.
When scaling the skin to 200%, the cover appears to be rendered at its original size and being scaled up afterwards, which makes it appear blurred like any scaled raster images.

Increasing the svg size to 384*384px (96 * 400% current maximum scale factor) fixes this.

The bug affects the spinnies as well. But there, I think the blurred version actually looks better than the oversized one, which is somehow missing proper anti-aliasing.

Probably there's already an unperceived blur at normal size, but it's not obvious since size in skin (111111px) doesn't differ much from svg size (9696px)
