I love kde, but can't stand some of it's bloat. Therefore, I usually just install kdebase and kdelibs, kdegraphics and kdemultimedia. I did this about a week ago on 5.9 RC1.3, and it worked fine. But today I've been unpleasantly surprised: I wanted to do the same on 5.9 RC2, but I get all sorts of trouble. For instance, the control center doesn't work (can't turn off those bloody sounds!).
The Slackware current kdebase+libs give me a fully functional kde desktop though.
