The scrolling and redrawing is actually fine if your system specs are pretty good (which yours are), the problem is that scrolling or any kind of moving/redrawing eats up the cpu so if something else is going on that actually needs the cpu then one or the other is going to get affected. I never really notice a performance hit, what I notice is the cpu temp going up and the fan noise along with it while the vid card temps stay at their normal (high) temps.

The trolltech/kde problem theory is a bit comical too. Of course they should fix what's obviously their problem that only affects one hardware vendors cards of certain models with certain drivers... so obvious.
