The main text application, not the plasmoid? 

Is this reproducible every time? 
What theme are you using?
Can you upload a screenshot.

Comment 2 Weng Xuetian 2012-04-20 03:43:04 UTC

It's plasmoid problem.

It's in Chinese, but you can see the last message is not shown completely.

Seems usually happen when I post something.

Theme is slim glow, but air also have the problem.

I think that this bug is fixed. See https://bugs.kde.org/show_bug.cgi?id=293522.
Should status change to "closed"?

Comment 4 Martin Klapetek 2012-08-25 17:08:37 UTC

No, this is not fixed. Fwiw, the scrolling is still completely crazy here on 4.9.

Fix scrolling

Workaround a bug in Qt #27592 where the ListView won't scroll to the end when
sections are being used. Dirty hack but seems to work correct.

Cache all the conversation in the ListView

Keep all the delegates in memory while showing. It could be a problem
if the conversation grows _a lot_ but it has to grow a lot.

Possible ways to solve it:
- limit the log lines that we'll be displaying. We're talking about a
plasmoid anyway. If the user wants to read the log, he'll use ktp-log-viewer.
- set interactive to false. Then we can scroll as much we want, but not with
the scrollbar
- buy a better aleix
