Every boot my mouse pointer speed is very slow. In the mouse system settings the pointer speed is shown as the correct setting, however it doesn't match the correct speed.
After changing the pointer speed the mouse behaves correctly again.
STEPS TO REPRODUCE
1. Boot into KDE
2. Experience slow mouse pointer speed
A slow mouse pointer.
The last set pointer speed in the settings module.
