Inkscape icons invisible except on mouse-over

Title says it: Sidebar looks empty, and even on mouseover when the icons appear, they’re kind of washed out. I’m using KDE, and Tumbleweed’s version of inkscape is 92.4. icon.svg file is present in usr/share/inkscape/icons, not sure whate else to check. --GEF

Nevermind - the problem was with my chosen icon set (in system settings).
