SVG desktop wallpaper is blurry

[Timo Laine]

With any SVG desktop wallpaper I choose, the sharp vector edges are blurred. In Inkscape, the edges of the same images are sharp.

I noticed that this only happens when the background is scaled, for example with the Zoom and Scale settings. It seems that the background rendering uses the same logic as with bitmaps: first it renders the background normally as a bitmap and then scales that bitmap while apparently applying a smoothing filter.

Naturally with SVG you should not do this but render the image from scratch every time you want to scale it to a different size.

Confirmed using /usr/share/icons/gnome/scalable/actions/forward.svg as background and style span. Other images and styles could be affected too but not so much.

Do you still get that issue in newer versions?

SVG wallpapers are still blurry at current disco.
