--- Comment #48 from Nate Graham <nate at kde.org> ---
There is no way to avoid blurriness when using HiDPI fractional Qt scaling with
monochrome line-art icons. The icons are designed to be pixel- aligned at 100%
scale, with the lines the thickness of one pixel exactly. But when you scale
them by 150%, the lines get 150% thicker yet the pixels on your screen don't
become 150% bigger. So the lines are no longer match the thickness of an
individual pixel anymore, and hence, they become blurry. There is no way to fix
this, sorry. It is simply something you need to live with when you use
fractional scaling.
