Hi, this bug is on openSUSE Tumbleweed with: KDE Frameworks 5.50.0 Qt 5.11.2 (built against 5.11.2) The xcb windowing system The kcm_mouse settings for some reason are much bigger than my configured system DPI (forced to 108) and it uses the wrong widget and color themes. (It appears to be using Breeze, and I use Qtcurve). I'll attach screenshots.

Just kcm_mouse? How about the workspace KCM or any of the ones in the Appearance category?
Do you have qqc2-desktop-style installed? The mouse KCM was ported to QtQuick, and only respects the platform QStyle via the qqc2-desktop-style bridge.
