Seems so. (string-match-p "GTK3" system-configuration-features) should 
tell more reliably, though.

Perhaps you icon theme doesn't provide scaled versions of the icons 
(mine includes .svg files for scaling) and GTK decided that it shouldn't 
scale the icons because of that.

Just guessing, though. I tried a bunch of icons themes already installed 
on my machine and couldn't repro, but they probably all do provide 
scaled versions of the respective icons.

And my GTK version is 3.24.20. Same Cairo version.
