You can't confirm your own bugs. Moving it back to UNCONFIRMED until someone
else confirms it.

It's blurry in macOS by definition. Increasing screen DPI to say 135 on Linux also makes it noticeable. 
Icons are also slightly fuzzy on windows with 96dpi screen without scaling

Comment 11 Telesto 2022-01-02 12:23:52 UTC
Raising priority a bit as a poke, because this matters for the first impression (and overall experience). It's optics issue only and not happening in all systems (you need to diverge from default, except for macOS. Ror the latter: the issue is also attributed to bug 141065

I leave it up to other to decide if the priority can be kept.. 

Number of people in CC is low (suggesting low importance), but well that was also the case for bug 100164 at implementation time...
Comment 12 Heiko Tietze 2022-01-03 10:22:11 UTC
Workaround is to use SVG icon themes.

Nope SVG quality really bad on Windows and macOS
Comment 14 Telesto 2022-12-21 23:23:09 UTC
A poke. The toolbar icons are really fuzzy (read low resolution pixelated) especially with a high resolution display like a Retina-display. macOS dark mode makes it even more noticeable, IMHO. It's not nice to look at, esthetically.

Screenshot: attachment 176406 [details] (inspect for example the new document icon)

Not limited to macOS, though.

Pixelated icons in Calc

I see pixelated icons in Calc as well.

BTW, is this a dupe of bug #51733 ?
