Yes, I'm aware of that.  I made sure to clear x-gtk-stock-map and
x-gtk-stock-cache before reaching these conclusions.

What I was saying is that, to my eyes, the way GTK scales these icons
results in less cognitive "blur" than the icons posted in the screenshot
attached by the OP, which seems to implicate Cocoa performing some kind
of "smoothing" operation on the scaled icon.

Or perhaps this could be an effect of viewing the OP's screenshot,
presumably taken on a high-resolution display, on my ordinary FHD
display.

Thanks.
