And you have. When reviewing posts I've made on Phoronix regarding KDE's lack of stability, even as far back as 2009, you've been there assuring anyone that'll listen that perhaps it's dbus or drivers or some other subsystem or sumsuch that's the real culprit.
You've maintained that KDE is stability personified for a very long time now. Yet you've also acknowlegded issues it has as well. You should make up your mind.
Winding back the clock to September last year we have this statement from you. I guess that must always be the distros fault.
Looking at KWin for example, even its developer acknowledges it's not in as strong a position as Compiz and friends, yet you assure us that KWin has no issues. It must have no issues as you've stated that KDE has none. Or are all KWins failings those of drivers? Thought so.
