            Bug ID: 94861
           Summary: Touchpad of T450s is not reliable on the bottom part
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium

The touchpad of the T450s is quite unreliable on its bottom part. When I land
my thumb on it and immediately trigger a click (when on clickfinger mode), the
cursor jumps up and down after the click.

Attached is a recording of my thumb clicking twice with the bug exposed.

This problem does not appear when using the software buttons, as the low part
of the touchpad is dead to movements (which makes it usable).

We might not be able to fix this besides "look, your touchpad can not do
clickfinger".
