A workaround for Fedora 24:

- erase the rpm xorg-x11-drv-libinput
- install (if not installed) the rpm xorg-x11-drv-evdev

Reboot your system. This is it.

Nevertheless this nasty bug should be fixed, because it affects many parts and
applications in KDE, not just Dolphin.

I just updated to 16.04.1via the Tumbleweed repos and I seem to get the
painfully slow version of this bug. I am on a 24" display with 2560X1440
resolution. 

Is there at least a workaround? It is really annoying.

for me, building the new dolphin from git master source on Mageia Linux x86-64
v6 does not seem to fix the problem. The only way I can get it to work is using
this patch that I don't expect to be applied as is :

[dolphin] [Bug 295571] Mouse wheel scrolling in Dolphin ignores global setting

(In reply to Shlomi Fish from comment #13)

When the real srolling distance (pixelDelta) is available, then Dolphin will
use it to scroll the content. This is exactly what the documentation of
pixelDelta [1] says: "The value should be used directly to scroll content on
screen." 

This bug (and also the patch) is about the case where no pixelDelta is
available.
