This bug has not been an issue for me for two years now. I just tested a
document with over 495,000 words with the gtk3 integration (the bug was only an
issue with the gtk3 integration). The good news is, the document scrolled
perfectly.

All the best

Dear vince.barwin...@gmail.com,

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

Addition to my previous comment: uninstalling libreoffice-gtk3 also helps.

--- Comment #12 from kunsten...@web.de ---
I updated today from Lubuntu 16.10 (LO 5.2. or 5.3.0) to 17.04 beta and have
now LO 5.3.1.2. (LO-Build-ID: 1:5.3.1-0ubuntu2) -  and I have now the same
problem with scrolling even small odts via touchpad on my compaq presario CQ61. 

SAL_USE_VCLPLUGIN=gtk libreoffice 
and
SAL_USE_VCLPLUGIN=gtk SAL_SYNCHRONIZE=1 libreoffice

both do help quite a bit, but I have the impression, scrolling with previous
versions of LO (and/or gtk?) were much smoother.

I'm running LO 5.2.1.2 on Archlinux (from the Arch Repos), and in my opinion
the bug is GTK3 related.

running SAL_USE_VCLPLUGIN=gtk libreoffice eliminates the bug for me, without
even using SAL_SYNCHRONIZE=1.

If I run libreoffice with GTK3 the problem reappears, even if i run it using
SAL_SYNCHRONIZE=1.

Some additional observations:

- This issue does not happen with the mouse wheel, only with the touchpad of my
Dell XPS 13
- Horizontal scrolling is way too fast, even with the workaround above. With
one little swipe, I'm already at columns AE-AR

Running a Gnome Wayland session (with gdm login manager).

I have the same problem with LibreOffice 5.3.0.3 in Arch Linux. Using:

SAL_USE_VCLPLUGIN=gtk SAL_SYNCHRONIZE=1 libreoffice

helps with scrolling issues.

Reporter emailed me again:

Presently I am using libreoffice 5.2.1-1 on Debian Testing. Recently I was
noticing very slow or sluggish performance even when opening small documents.
Small spreadsheets were  taking about 10 seconds or more to open for example. 
I googled this problem and found I was not alone.

However, when I executed the magical:

SAL_USE_VCLPLUGIN=gtk SAL_SYNCHRONIZE=1 libreoffice

the sluggish performance is gone! --- Because I think,it is not using the bug
riddled gtk3.

Reporter again emailed me privately:

I just did the two quick experiments.

The first,

SAL_USE_VCLPLUGIN=gtk libreoffice

still produced the bug.

However, doing the sync with 

SAL_USE_VCLPLUGIN=gtk SAL_SYNCHRONIZE=1 libreoffice

eliminated the bug.

(end of quote)

Caolán just posted an explanation of what the synchronize variable does:

--- Comment #4 from Buovjaga  ---
Vince: maybe you could do some tests without touching the libreoffice-gtk3
package.

See, if you can reproduce the problem by running libreoffice from the terminal
with the command:
SAL_USE_VCLPLUGIN=gtk libreoffice

If you get slow scrolling with that environment variable, you could next try
this bit of sorcery:
SAL_USE_VCLPLUGIN=gtk SAL_SYNCHRONIZE=1 libreoffice

The results of these experiments might be useful information for developers.

--- Comment #3 from Buovjaga  ---
Reporter sent this private mail:

Just over a week ago, I replaced my Sparky Linux based on Debian Testing
Stretch with pure Debian Testing Stretch. It had Libreoffice 5.2, and it
initially worked fine. However, a few days later after installing and
uninstalling software to get my system the way I wanted, suddenly, the same
problem with Libreoffice writer returned. I ended up submitting a bug report to
Debian just last Sunday, and on that same day, someone from the Debian team
suggested to me the problem may be related to
libreoffice-gtk2/libreoffice-gtk3, and to execute the command

dpkg -l libreoffice-gtk2 libreoffice-gtk3

When I did,I got the following output:


Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ NameVersionArchitecture  
Description
+++-===-==-==-
ii  libreoffice-gtk21:5.2.0-2  amd64  office
productivity suite -- GTK+ 2 integration
rc  libreoffice-gtk31:5.2.0-2  amd64  office
productivity suite -- GTK+ 3 integration

What is critical here, is that while I was installing/uninstalling software, I
must have unwittingly uninstalled
libreoffice-gtk3 while I think I was uninstalling the buggy Mate desktop which
had been giving me grief. My main desktop is Xfce.

When I reinstalled libreoffice-gtk3, the problem disappeared. Now when I scroll
or do searches on a large document, libreoffice writer works fine. As well, the
Mate desktop, having switched to gtk3, seems to me, much less stable.

Another thing. This problem only became apparent on sizeable documents like 50
pages or more. For say just eight pages, there was no problem. Hence, this is a
bug that for most people would be hard to detect. However, I work on documents
over 500 pages, so for me, this bug made libreoffice writer almost unusable.
