Created attachment 70293 [details] testcase The text in all lines after a line that has the dot.png image in the testcase seems to draw one pixel earlier than it should, and this effect seems to accumulate. I've stripped down the example from my nagios report where I usually see this.
I can reproduce this with self compiled 4.9.1+. It's interesting that 1) if I scroll new lines are rendered correctly 2) if I reload several times sometimes all is rendered fine.
Starting konqueror with "-graphicssystem native" fixes the issue form me. See also bug 290371.
Dear user, KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6. Please migrate to use a QWebEngine based HTML component. We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes. For security issues, please see: https://kde.org/info/security/ Sorry that we did not fix this issue during the life-time of KHTML. Greetings Christoph Cullmann
