🐛 [BUG] - SP4 touchscreen acts as a touchpad

[Freakishink292]

Description

When I tried to use the touchscreen on my Surface Pro 4, I noticed it was moving a mouse cursor when I dragged it. Is this an intended feature or is there some sort of issue with this? My SP4 is the Core m3 version.

Reproduction steps

1. Drag touchscreen
2. Mouse cursor moves

Can you please reply with the contents of the following command:

dumpsys input

No command dumpsys found, did you mean: Command dumpe2fs in package e2fsprogs Command dumpsexp in package libgcrypt Command dumpcap in package tshark from the root-repo repository Command dumpcap in package wireshark-gtk from the x11-repo repository

It looks like the SP4 has 2 components related to touch, so an IDC per device might be needed.

I'm seeing the same issue (touchscreen working as touchpad) on a Surface Pro 7.

As @Freakishink292 reported, the dumpsys command does not appear to be present.
