Description zhulik 2015-12-10 19:19:39 UTC

I have laptop with great trackpad and i noticed, that scroll in dolphin main view isn't smooth and pixel-perfect like in nautilus. Also, it don't scrolls like mous, with small steps, it scroll only with big steps, only when i quickly move my fingers over all touchpad suraface. I have 4k display and synaptics touchpad, if it's important.

Reproducible: Always

Steps to Reproduce:
1. Open dolphin
2. Try to scroll files

Actual Results:  
Scrolling only with big steps, only when i quickly move my fingers over all touchpad suraface.

Expected Results:  
Smooth, pixel-perfect scrolling like in nautilus

ArchLinux latest, plasma 5.5, dolphin 15.08

I have the same issue. This ONLY happens when InvertVertScroll is set to true in touchpadrc. (i.e. scrolling is inverted) This does not happen in Dolphin4 or any other application.

Update: This does not happen with libinput, only with the synaptics driver.
However touchegg does not work with libinput so I'm currently stuck with the synaptics driver.

Please try again with Dolphin >= 16.08 and reopen if you are still affected.
