--use QtControls 2.2 for Sliders in dock settings
and update the Latte required version to 5.9 which
is LTS. Most distros should have already updated
to that one.
-as it appears the PlasmaComponents3.Slider
was adding too much visual distraction. I had
to fork it in order to use it dock settings
window. We needed the behavior of wheelEnabled
in order to disable it and the only slider
providing it from Qt 5.7 was the QtControls 2.0
Slider
--fork the PlasmaComponents Slider in order to
update to newer Qt version and support the
wheelEnabled property. After that just disable
wheel for all sliders in Appearance page.
