[SOLVED] Scrolling in QT Apps hops after changing selection

Good morning everybody,

I am using Arch for a while now together with Plasma.

Everything is fine except this one Scroll bug:
The first scroll movement jumps to the end or the middle and then continues normally.
If you then scroll to a position, select an element and then continue scrolling, it first jumps in the wrong direction and then continues scrolling in the right direction.

This only affects QT Apps with lists like Dolphin, Amarok and Octopi but also the webview of Qupzilla. GTK Apps don't seem to be affected so far.
I don't know if it affects scrolling in general as you are usually not scrolling aside from lists. Okular and LibreOffice(QT) don't show this behaviour.

Especially for Qupzilla this is very annoying, so I'll appreciate every help and ideas you have!

Can't confirm, how do you scroll? Touchpad? What is your input driver ? try switching between libinput and evdev (and/or synaptics in the touchpad case)  respectively. FWIW I use the evdev driver with a normal USB mouse.

Thank you for your quick and helpful response!

I was using evdev with a normal usb mouse.

Installing xf86-input-libinput seems to fix it. Well I didn't suspect that it was a driver issue as it only affected QT Apps.

A bit sad that it was so easy and I lived with this annoying bug for months!
But anyway I have a forum account now, so it also had a positive aspect!

Thank you very much!
