Hi,

Description:

I'm hit by a trackpad bug in the new libreoffice-fresh 5.1.0-1 version. This bug has been confirmed and patched in Red Hat bugzilla. Patch cherry picked by freedesktop/libreoffice with more information:

https://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-5-1&id=b083afac2f0531bacd790cb3ac25353f9a02db5d

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=809363

https://bugzilla.redhat.com/show_bug.cgi?id=1294208

Additional info:

- libreoffice-fresh 5.1.0-1
- X.Org X Server 1.18.1, standard configuration loading synaptics module ver. 1.8.3

Steps to reproduce:

1.) Run LO-fresh 5.1.0-1 on laptop with Synaptics touchpad, using X.Org synaptics module.

2.) Load document that spans multiple pages vertically.

3.) Use mouse to drag vertical scrollbar down to scroll document a long way down.

4.) Try to use vertical scrolling on touchpad, either two finger or edge scroll. Document scrolls upward rapidly which is not expected behaviour.

HTH.

Try use:

export GDK_CORE_DEVICE_EVENTS=1

/usr/bin/soffice

It works! Thank you for this work-around :)

I did a search and found this comment:

[18:51] <amigamagic> I found this on a forum thread from 2012 (http://forums.gentoo.org/viewtopic-t-925138-start-0.html): "If you export GDK_CORE_DEVICE_EVENTS=1, GDK will stop using XInput and use old-school X11 events"

in this IRC log:

http://irclogs.ubuntu.com/2014/05/14/%23xubuntu-devel.txt

FWIW, the problem would appear to be related to XInput, while using X11 events works.
