I just did a reinstall of Solus Plasma and this time I DID NOT copy over any old settings, so this is as fresh and clean as possible. However, Kvantum doesn't seem to work. I installed it through the Software Center, then installed a theme and selected kvantum as widget style, but it doesn't work. All apps keep using Breeze. A reboot also didn't help. It's NOT the theme's fault as it's compatible and it worked before the reinstall.
