I've installed Plasma KDE on Ubuntu 20.04 and after i uninstall it with this command (which i found here):
sudo apt --purge autoremove plasma-desktop-data plasma-workspace kded5 libkf5plasma5 libkf5runner5 kactivities
These weird white box started appear on some applications like Software, dconf Editor, System Monitor,...
This happened with every dark theme like yaru-dark, flat-remix,...
Is there anyway i can fix it ? Thanks !
