Well, i found THE solution to problem. Apparently, the laggines is solely due
to QT. I found on some forum, that there is apparently a new way of rendering
that will be soon the default for Qt4 apps. However, it can already be tried
out by:

<qt/kde-app> --graphicssystem raster

So for dolphin this is:

dolphin --graphicssystem raster

With this new system everything is absolutely smooth. For me it is already
stable, although it is still considered not. IMPORTANT: for dolphin, you need
to kill all dolphin processes before trying this out, otherwise it won't work.

Also all other apps i tried run much smoother now (especially kile).

So finally, i think this bug report can be closed as it is not kde or dolphin
specific and a solution is almost there.
