Same problem on Dell Inspiron 16 7620 2-in-1, Linux Mint 23.1 Cinnamon
(x11 session).

LibreOffice Writer Versions tested:

Version 24.2.1.2 (X86_64) / LibreOffice Community
Build ID: db4def46b0453cc22e2d0305797cf981b68ef5ac
Flatpak

Version: 7.3.7.2 / LibreOffice Community
Build ID: 30(Build:2)
(This is the version that Mint 23.1 includes by default.)

Both versions show CPU threads: 16; OS: Linux 5.15; UI render: default;
VCL: gtk3; Locale: en-CA (en_CA.UTF-8); UI: en-GB

Cannot scroll vertically by swiping up or down on the touch screen with
one or two fingers. Same problem in Normal or Web view. It works on the
touch pad but that can be difficult to use, due to disabilities or when
the laptop is inthe "easel" configuration (keyboard and touch pad on the
bottom, facing the desk, screen upright, rotated 180 degrees compared to
regular laptop configuration).

Also, cannot move the vertical scroll bar up or down by touch on screen,
in Normal or Web view. Touching and holding the "handle" icon does not
allow dragging it up or down. Tapping above or below the "handle" icon
on the vertical scroll bar works but it's an imprecise way to move
through the document - usually moves more than a few lines at time.

By comparison, OnlyOffice Document (word processor) and Firefox browser
on the same platform also does not allow one or two finger swipes
up/down on the touch screen to scroll, but at least the vertical slide
bar  on the touch screen works as expected.

The Mint text editor, xed 3.4.5, allows vertical scrolling with one-
finger swipe on the touch screen.

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

Status in LibreOffice:
  Confirmed
Status in libreoffice package in Ubuntu:
  Confirmed

Bug description:
  Ever since I upgrade to 20.10 from 20.04, I have been experiencing this issue.
  There are times when a user might want to scroll their screen by touching 
their screen. But I can't do this anymore.

  I want to know what went wrong? What can I do?

  Any info is appreciated.

  Note:
  Currently, I can scroll without in issue in Nautilus. But I can't do the same 
in Firefox, Tor browser, Libre Office, etc. Except Nautilus, all apps select 
words on screen whenever I touch my screen to scroll. 

  But we all know, SCROLL ≠ SELECT.
