I've noticed with the touchpad on the late-2017 Razer Blade Stealth (with the
i7-8550U), there's a deadzone slightly off-center.

Running kernel: 4.16.0-041600rc4-generic
libinput: built from master at cd966460

The touchpad works fine in Windows, however does not work under Ubuntu (tested
17.10 and 18.04) or Fedora 27. It also occurs on both Wayland and X, and with
both the Synaptics drivers and libinput. The issue appears less significant
when using libinput, but still constant.
If a finger enters this zone, it will register the following in the logs:
> touch 0 from BUTTON_STATE_AREA, event BUTTON_EVENT_UP to BUTTON_STATE_NONE

Occasionally, when a finger is held in that zone, the cursor will seemingly
vibrate.

The device information is:
