I know there has been a number of blurry/pixelated icons in retina/hidpi screen during the last years, but I don't believe any of them is addressing this case (one report of blurry icons was marked as duplicated as a report of pixelated icons, which is a very different issue). Also, using the svg version if the icons makes things even worse.
Steps to Reproduce:
1. Open writer
2. Look at the toolbar icons
Icons are fuzzy like in the attached screenshot.
Icons are crisp, not scaled, not antialiased or whatever it's being done to them. In particular, SVG icons scale without fuzziness.

I meant to say "blurry/pixelated icon reports".
Personally, I think this is a DUP of bug 51733.
Comment 15 mentions blurry icons.
Comment 34 indicates that the problem is linked to HiDPI support (or lack thereof).
