Public bug reported:
My touchpad works normally except for two-finger scrolling, where it
frequently jumps/skips instead of scrolling smoothly. I was originally
using libinput drivers and switched to synaptics drivers, but it did not
resolve the issue. I am hoping to get some help identifying the root
cause
