Bug 252412

Summary: Screen jumps (scrolls) down when typing after scrolling up
Product: [Applications] kate Reporter: niburu1
Component: partAssignee: KWrite Developers <kwrite-bugs-null>
Status: RESOLVED DUPLICATE    
Severity: normal CC: cullmann
Priority: NOR    
Version: unspecified   
Target Milestone: ---   
Platform: Ubuntu   
OS: Linux   
Latest Commit: Version Fixed In: 4.8.5

Description niburu1 2010-09-26 12:25:11 UTC 
Version:           2.1b4 (using KDE 4.5.1) 
OS:                Linux

If I scroll down so that the cursor is located above the last VISIBLE line of the page, when I start typing the screen jumps up. Where the screen jumps to depends on where it was previously (i.e. it doesn't jump to a fixed place).

It did not do this previously on my system before I installed some updates from the Kubuntu 10.04 backports repository.

Reproducible: Always

Steps to Reproduce:
1. Open or create a new document that has more than a page of text.
2. Scroll down so the cursor is located above the last VISIBILE line (not necessarily the last absolute line of the document).
3. Type something.

Actual Results:  
The screen jumps up.

Expected Results:  
The screen doesn't jump.

Sorry, but I can't reproduce this here. But just in case I'm forwarding this to KatePart.
Comment 2 niburu1 2010-10-02 17:21:44 UTC 
It still occurs on my system after an update to Kubuntu 10.10 RC. It looks like it might be a bug located in the "Autocenter cursor (lines)" feature.
Comment 3 Christoph Cullmann 2012-11-07 23:19:28 UTC 
I can't reproduce either, even not if I say auto center for example 1 or 3 lines.
Comment 4 Dominik Haumann 2012-11-08 09:43:41 UTC 
Christoph, you fixed that yourself for KDE 4.8.5 :-)
