I am not excusing KDE here, I can't be sure but there is a chance that is a packaging/distro issue. My question was for OP to present the fundamental UI issue, I am sure there are hundreds or touand of bugs in the KDE bug tracker but I am not aware of a fundamental issue unlike the other popular DE that has a major architectural issue .
