AGPFastWrite doesn't change anything!

The Effect doesn't depend much on the number of sites displayed in Konqueror
window but it depends on kind of sites displayed. You've noticed, that it seems
to depend on the presence of constantly moving banners and this may be the most
often appearing reason, but not the only one: I've found probably the best
example to test this effect:

http://www.t-com.de/is-bin/INTERSHOP.enfinity/WFS/EKI-PK-Site/de_DE/-/EUR/ViewFAQTheme-Download;sid=JUkm0gWAGG8m1EA89pQsSiSu0PhBhuEXO2z_JTIVm9AIe_AxQh0=?ProductThemeId=theme-1000&selaction=themen&FaqId=theme-2001628&pageNr=0&bound=3&itemLocator=Bedienungsanleitungen&headerSelection=2&SelectedTheme=theme-2000178&SelectedTheme=theme-2001628&SelectedTheme=theme-9152828

Sorry for the long URL, but this sites dosn't display any moving banners
(surprisingly there are not even big static images...) but causes Xorg to
consume nearly all CPU time when opened in Konqueror. In Firefox, it's
displayed very smoothly!

After 20 Minutes of web-surfing, partly on sites, where the problem occurs (to
point it out for you), I get the top-"screenshot" attached below. My System has
1.5 GB RAM, doesn't seem to swap in this situation and CPU-frequency was
manually set to 1.6 GHz (which is maximum).

Could this thread on kde.org be related to our problem:

http://lists.kde.org/?l=kfm-devel&m=114796919602629&w=2

There, a similar problem is reported for NVidia cards. Down in the thread there
are some Qt-Patches made responsible for this behaviour
(http://lists.kde.org/?l=kfm-devel&m=114802781929549&w=2).

Hope it helps and thanks for caring about
