Description Silver Salonen 2010-03-22 06:39:33 UTC 
Version:            (using KDE 4.4.1)
Installed from:    openSUSE RPMs

I have dynamic wrap enabled. I've written quite long texts onto the same line and when I slowly, carefully scroll the document, I see it jumping forward from one line to another (as a top line). It makes scrolling very jerky and thus quite difficult to follow in means of document length.

Thats by design, sorry, that is not changeable.
Comment 2 Silver Salonen 2011-06-26 06:47:03 UTC 
What design is that? The design needs to be fixed then, because it's a buggy behavior of a program.
Comment 3 Christoph Cullmann 2011-06-26 10:59:15 UTC 
Thats your opinion and if your want to rewrite that part and provide patches, than it is fine. But that is no error or bug.
Comment 4 Silver Salonen 2011-06-27 06:08:59 UTC 
Sorry, maybe I soundid a bit harsh before :)

I thought about that a little, so yes, that may not be an error in design, but maybe the bug should be changed to wish instead? The wish would be to enable line-by-line navigation with dynamic line wraps.
Comment 5 Christoph Cullmann 2011-06-27 06:13:54 UTC 
Ok, thats a valid thing to do :)

What could be done is this: Check, if the upper line is dynamically wrapped. If so, move the view one line up, but do not touch the scrollbar.

Then, at least scrolling with the mouse wheel over the text area would work as expected.

KDE 4.8 seems to have this issue solved (at least for me).
Comment 9 Silver Salonen 2012-02-10 11:46:05 UTC 
Yep, seems fixed.
Comment 10 Dominik Haumann 2012-02-16 21:15:07 UTC 
Yes: It works with the arrow buttons of the scrollbar and the mouse wheel.
But it does not work, if you move the scrollbar with the mouse.

But I think this is still a good compromise.
