Title:
Multi touch broken on lunar (23.04) (xorg + wayland) for Focaltech

Bug description:
Multi touch broken on lunar (23.04) (xorg + wayland) for Focaltech
touchpad
Since the upgrade of my laptop (ASUS Zenbook UX303UB), multi touch has
been acting erraticly in the following situations:
- two finger scrolling
- one finger clicks left mouse, other finger drags
when two fingers are moving onto the surface, the cursor is fleeing to
the right/top of the screen. (See attached screencast)
The issue happens regardless of xorg/wayland.
I enclosed a screencast video that demonstrates the issue. In this
scenario, I am moving a window downwards using two methods:
- Click and drag with one finger : working
- Click the left click area with one finger, and drag using the other : not
working, cursor is fleeing
- When two fingers are present, and one of them is moving, I am experiencing
the "fleeing cursor" issue
Workaround : using left edge scrolling works as temporary workaround
for scrolling, but click drag using a single finger is really
cumbersome.
Here is the output of the `xinput` command on Xorg:
