KDE3 Konsole output too slow

I am install opensuse 11.1 (before was 11.0) with KDE3. And now Konsole from KDE3 works very slow (for example, when I PgUp-PgDown in “less” command I can see how lines of text are redrawing).
I am upgrade all KDE3 libraries from repository - no effect.

In KDE4 Konsole - all is fine and fast, but there are strange text-line interval, that I can’t remove by changing fonts and can’t found any config for this.

Is someone else have the same problems or solutions?
