Bug Description
When using normally the touchpad, sometimes it jumps to (mostly) the bottom of the screen. It jumps to any position in the bottom, not the corners.
Also, sometimes it jumps to the top. This is not random jumping, or erratic movement. It jumps to the bottom on some touchs.
I found that it's quite reproducible if you play a little with two fingers on the pad, not moving the pointer but just touching the pad with one finger, then with the other, then with the first, etc, in rapid succession.
I'm happy to help with any debugging.
