Bug#822081: gnome-control-center: Mouse settings have no effect since 3.20

[Andreas Hehn]

Package: gnome-control-center
Version: 1:3.20.1-1
Severity: important

Dear Maintainer,

since the update of gdm3, gnome-shell and gnome-control-center to 3.20 the
mouse settings in the control center have no effect anymore.
Neither the "Mouse Speed" slider nor the "Natural Scrolling" switch work as
expected.
The actual mouse speed remains the same and scrolling with the touchpad is always un-"natural".
I can't tell whether the "Primary Button" switch works as expected, because it's not entirely clear to me what this setting should do (swap effects of left and right mouse key?).
I would appreciate if you could have a look into the matter.

Best,

Andreas
