Description: The svg icons are 'blurred' compared with the non-svg versions. It looks like the rendering of small details like narrow lines does not work properly Steps to Reproduce: 1. enable svg icons 2. 3. Actual Results: they look different to the bitmap versions Expected Results: they look the same as the bitmap versions Reproducible: Always User Profile Reset: No OpenGL enabled: Yes Additional Info: see att.
Created attachment 152801 [details] svg icons (above) compared to the standard ones; Breeze theme
The SVG icons are not rendered directly to UI, rather they respond to the scale of the os/DE UI and are scaled and written to icon cache as PNG. They really do not offer any improvement over the prebuilt PNG until display scaling is over ~175%. For example when working on a HiDPI 4K display. So what size and resolution monitor are you using, and what UI scaling have you compared? Otherwise WFM and => NAB @Tomaž, would you agree?
The screenshot is taken on 1920*1080 monitor without any scaling. I do not know what the abbreviations mean, but I guess it is up to the developers/you.
Created attachment 152813 [details] rendering of PNG vs SVG icons at scale In attached clips, on left is Colibre PNG scaled to 250%; on the right is Colibre SVG scaled to 250%. Windows 10 on a 1920 x 1080 px screen. At 100% scale, the details of the SVG will be "fuzzy" compared to the PNG--but when UI is scaled (by user or in response to HiDPI hardware) the improved clarity and readability fo the SVG icon sets are pretty apparent.
Well, it kind of is a bug, but it's known. Our SVG renderer in LO has bugs (and in some cases even bugs in rendering backend), that's why the icons are fuzzy (most likely a wrong pixel position is calculated and we hit somewhere in between pixels, so the result is blur). Ideally SVG should be the same quality as PNG (as PNG are made from SVG using inkscape), but that's currently not the case so SVG support is considered experimental. Once the SVG renderer will be fixed, we will start thinking to remove PNG icons as SVG icons take less space and can render to different scaling factors.

Thank you for the information, I'm glad that the issue is known and I look forward to it being eventually fixed when the time comes.
