            Bug ID: 354498
           Summary: scrolling after click or select several times in any
                    kapplication with logitech wired mouse cause scrolling
                    backwards or jump
           Product: kde
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: arkbriar at gmail.com

When I do some selection or click some times in konsole (there's text long
enough to scroll), and scroll after that will cause jump (lines, even pages,
and maybe forward or backward) everytime!

I can reproduce it in almost all of the kapplications. However, gtk based
applications(chrome / Thunderbird / gvim ) work well. 


Reproducible: Always

Steps to Reproduce:
1. open Konsole or System config
2. scroll down with middle button, it behaves normally ( 3 lines down on my
machine, smoothly)
2. generate a long text in Konsole and do selection at least 2 times , or click
some icons in System config
3. scroll down with middle button 
4. AND THEN it will jump lines, sometimes pages( as scrolling continuously you
could see the selected text!

Actual Results:  
 It will jump lines, sometimes pages.

Expected Results:  
scroll the lines specified in config, it's 3 lines on my machine

The first time i met this problem is when i was testing Kubuntu 15.04, Plasma
5.3. And I have never met this problem on my Kubuntu 14.04 with Plasma 4. 

Here is the detailed environment now:
Hardware: Toshiba satellite l800
Platform: openSUSE Tumbleweed x64
kernel: 4.2.3
KDE Plasma: 5.4.2
Mouse: Logitech G300

I have tested my roommate's Logitech wireless mouse and i could't reproduce
this. But when i have the two mouses both plugged in, I could reproduce it with
his mouse.

I hope you could find how to solve it. It's really annoying.

Finally, thanks for your efforts!
