Unfortunately, they do need to be re-generated, or you
will get what you see: The old file with the new picture.
Ok, I regenerated
Kate's help files and the title now looks ok (white color, on the leftish side).
But the bottom part still shows the old blueish KDE color and the horizontal ribbon as
well. I can post a screenshot if required.
When are these files generated? At build time or the
first time they are open?
They are generated at build time, often stored as a zip
archive.
