I get a similar problem with Konqueror 4.2.3. Sometimes, the scrolling feature brokes : only the top port or the bottom part of my page is refreshed. The problem occurs in all opened tabs. I have to close Konqueror and to re-open it to solve the problem.
Strangely, the problem never occurs in Akregator (as I think it uses KHTML too).

For me the problem isn't linked to the graphic cards (I have an ATI with proprietary fglrx drivers) because I reproduce the problem with remote connection through the NX server and NX client.

I'm using qt-4.5.1.
I'll try to post a screenshot and the next time, I reproduce the problem.

Same here on OpenSUSE 11.1 with KDE 4.2.4

I reproduce the problem with konqueror-4.2.96 and qt-4.5.2.
Comment 7 Frédéric COIFFIER 2009-07-16 08:46:06 UTC
Today, I have reproduced exactly the same problem in the treeview widget which contains the list of feeds in Akregator. So, it's not linked to KHTML or Konqueror. The problem seems to be more generic.

So, the bug can be in Qt itself or in Kdelibs if Kdelibs customize the scrolling/refresh mechanism : Is there a Kdelibs developper to confirm that ?
Comment 8 Frédéric COIFFIER 2009-07-30 21:33:12 UTC
When I get the problem, the mouse cursor no longer reacts to URL : it doesn't change from arrow to hand. But, if I click on the link, it works.

I know that Qt support different backend like raster, X11 or OpenGL. In my case, I'm using the usual X11 backend.

This seems to have more duplicates: 202405 and 194291
