Touchpad Acceleration Speed Drops Randomly
Summary
Touchpad acceleration speed drops randomly. The script in the video sets the acceleration speed high and low to give you a demonstration: https://www.youtube.com/watch?v=m_FLk-0wm38 (I'm making the same hand movements throughout the video)
Also there is another user who has the same problem with the same laptop, here is the Arch forum thread of the issue: https://bbs.archlinux.org/viewtopic.php?id=272654
Steps to reproduce
Problem doesn't occur when in battery mode, even after hours of usage. It happens when charging but not right after plugging the charger, sometimes it just doesn't happen at all. Also it doesn't go back to normal after unplugging the charger.
