Brilliant Upgrade, thanks for the hard work put in to make it so.
I've basically looked over my settings and all is well.
Tried my minimal destop effects, Alt+Shift+F12, no hiccups.
Icons in left of Panel, Konsole, Synaptic, Configure your Computer, and Configure your Desktop, are smaller than before. Shall look into that when have a moment.
Thankyou for what seems a painless KDE update. Small steps are obviously easier on everyone all round.
