See the screenshot taken on Arch Linux, plasma 5.13.3.
User manager and power saving icons look fuzzy.
Can reproduce. If you look closely, the circular icons in the sidebar have the same glitches.
bug persists in plasma 5.15 beta.
Operating System: Arch Linux
KDE Plasma Version: 5.14.90
KDE Frameworks Version: 5.54.0
Qt Version: 5.12.0
problem is if it scales a non integer number of pixels, by definition things cannot be pixel perfect.
in the end the choice is between having a sharp but glitchy image or a bit blurry.
Given those options, blurry is much better than glitchy IMO.
Turns out it's a double scaling in kiconloader, after all.
(not that after the patch the icons are still not perfect because they can't, but immensely better)

Fix padding icon that doesn't exactly match the requested size
The size we get already takes into account scaling, so we end up creating a pixmap
whose size was scaled twice and then had the view scale it down again.
