I can confirm this issue is still present with current LibreOffice
releases.

**System**

* Hardware: ASUS ZenBook UX303LB with Atmel touchscreen (10-touch)
* OS: Linux Mint 22.3 Cinnamon
* Kernel: 6.17.0-35-generic
* LibreOffice: 26.2.5.2 (Ubuntu package `4:26.2.5.2-0ubuntu0.24.04.1~lo1`)
* VCL: gtk3
* UI render: default

**Testing performed**

The touchscreen hardware and input stack have been verified to be
working correctly:

* `xinput` detects the Atmel touchscreen.
* `xinput test-xi2` reports normal `RawTouchBegin`, `RawTouchUpdate`, and 
`RawTouchEnd` events while dragging a finger on the screen.
* `libinput` is in use.
* The issue occurs with both:

  * Cinnamon (X11)
  * Cinnamon Wayland (Experimental)

I also tested different LibreOffice VCL backends:

* `SAL_USE_VCLPLUGIN=gtk3` → no touchscreen scrolling
* `SAL_USE_VCLPLUGIN=qt6` → no touchscreen scrolling
* `SAL_USE_VCLPLUGIN=gen` → no touchscreen scrolling

**Comparison with other applications**

On the same system and using the same touchscreen:

* Brave: touchscreen scrolling works.
* Firefox: touchscreen scrolling works under Wayland.
* Thunderbird: touchscreen scrolling works under Wayland.
* LibreOffice Writer: touchscreen drag does not scroll the document.

This suggests the touchscreen hardware, kernel, libinput, and
Wayland/X11 input stack are functioning correctly, and the remaining
issue is specific to LibreOffice's handling of touchscreen scrolling
events.

other GTK applications work correctly on the same system

In the same Wayland session, Firefox, Thunderbird and Brave all support
touchscreen scrolling correctly. This indicates the touchscreen
hardware, libinput and Wayland input stack are functioning normally, and
the issue appears to be specific to LibreOffice.

Title:
  Touchscreen can't be used to scroll anymore. Instead it will select
  everything on its way.
