from the threads I posted it should be clear that kde4/qt4 are not the only
ones affected. gtk is slow too. So is firefox. On Intel integrated graphics,
qt4/kde4 is fast and fluid. That should give someone food for thought.
I bought an Ati because I was fed up - and while it is not perfect, it is so
much better that I am glad that I did the jump. Using xshm instead of xv for
video is a small price, for not having to wait several seconds until the
desktop reacts on a right mouse click or have krunner work as soon as it is
open.
Also the 7300 is a bad example - it is a very slow card. And the big 8 and 9
cards hide some of the slowness because they are so powerfull that it makes up
for some of the shitty drivers.
The worst part - Nvidia knows about this for ages - and nothing happend.
