Unrelated, but does anyone know how to get rid of the shitty monochrome icons that semi-recent (Debian stable) KDE uses by default (even for popular non-KDE applications) and restore the actual ones shipped with the applications (and of course, make the rest clear)?

I spent some time in systemsettings5 changing theme options but the only breakage I managed to (partially) fix was the titlebar.

I think you mean 'Breeze'. I think to have other icons, you just need no select a different icon theme, if you installed one, but please not Adwaita :)
