Description Christian Boltz 2018-01-01 21:20:03 UTC
Since a few days / some Tumbleweed snapshots (looking at /var/log/zypp/history, the Qt and KDE updates in 20171223 might be a candidate) I noticed a funny 
scrolling problem in KMail.

When reading a long mail (for example a Tumbleweed snapshot announcement), I can scroll down with the "page down" key exactly once. Pressing page down again does nothing, even if there's enough text left to scroll down.

If I scroll up again, the "page down" key works again exactly once to scroll to the "second page", and then it stops to work.

I can scroll down with the "down arrow" key (slowly of course) until the end of the mail.

Scrolling with the mouse also works until the end of the mail - both by clicking the scrollbar and by using the mouse wheel.

Oh, and if I scrolled down with the down key or the mouse, pressing "page up" brings me to the beginning of the mail, as if I had only scrolled down by one page. Even more funny - pressing "page down" scrolls up to the second page.

This bug was confirmed by some people on the opensuse-factory mailinglist.

I can confirm this also on the current git master state. Can you file this upstream?
Comment 2 Christian Boltz 2018-01-01 22:39:54 UTC
Thanks for testing with the git version!

Submitted upstream as https://bugs.kde.org/show_bug.cgi?id=388440

Laurent was really fast in fixing this upstream :-)

Is there a chance to get
into the openSUSE packages with similar speed? ;-)

Thanks for the quick reaction!

I installed messagelib and messagelib-lang from KDE:Applications, and can confirm that "page down" works again :-)
