Public bug reported:

Binary package hint: konqueror

Using kubuntu jaunty, the following problem has developed since a
updating my system today.  I had not updated since a week previously, so
this is must be caused by some package update done between 2009-02-13
and 2009-02-21.  I'm guessing it is a Konqueror bug, but it could be
some other display thing.  I'm using the radeonhd driver, on a Dell
Studio 17.

In Konqueror (and also in another app which I think use konqueror's
rendering engine for HTML, BibleTime), the window does not update
properly when scrolling.   Sometimes the window doesn't update at all,
at other times I get garbled output.

Sometimes it works fine, then suddenly develops the fault.

Some sites are much worse than others e.g. reddit.com seems to be fine,
launchpad.net is awful - I'm using Firefox to file this bug, because
konqueror is completely unusable on this site.

I've attached a screenshot of what I get after going to
https://bugs.launchpad.net/ubuntu/+bug/50517 and scrolling down.  When
you are actually moving, it's much worse and more confusing than the
screenshot suggests, but you can still see the confused mess on the

konqueror 4:4.2.0-0ubuntu3
