Palm touches

I've attached 3 recordings of palm touches. All of them are pretty similar: my
right palm is touching the touchpad when I either use the keyboard (but I'm not
typing constantly) or is resting.

By the way, here is the evemu-describe for the touchpad in PS/2 mode (which was
used for these recordings):
