So, as soon as you mentioned this, I realized that made so much sense that I don't know why I hadn't realized it before now.
I only did a brief check but the Adwaita theme definitely uses more .pngs than .svgs and it seems reasonable, to me, that could be the cause.


I had noticed that the core-updates-frozen branch had been merged so I upgraded but found things pretty much the same as before.
I saw an old patch (http://git.savannah.gnu.org/cgit/guix.git/commit/?id=e311ef4f87f7ad8db2114e5f89961eea0240893b) and, while I'd checked rofi for gdk-pixbuf+svg – before –, – somehow – it made me think to check librsvg, this time, and found that it was using gdk-pixbuf, rather than gdk-pixbuf+svg. I then made a package inheriting librsvg but using gdk-pixbuf+svg, instead, and made a package which inherited rofi but used my librsvg package and, with that installed, rofi worked with .svgs, then.

Am I right in assuming librsvg ought to be using the latter, as the library deals directly with handling SVGs? If so, I can put together a patch to submit.
