Re: Please stop that bashing...
it is not like that only kde 4.1-rcX were hit by thig driver bug! If it were that way nobody would complain.
Some simple facts: the problem is known for month.
Not only KDE 4.1 (which is btw final) is hit by this problem, KDE 3.5 is hit too - just not as severe. So some people think 3.5 is problem free - it is not.
It is not a KDE problem, because gtk apps suffer too.
Until now there is nothing to really solve the problem. The only solution is either to buy a 7XXX card or a 260/280. Or go ATI.
Ati is not perfect, but the symptoms are much less severe.
