Description Yousuf Philips (jay) (retired) 2014-10-06 07:59:19 UTC
When elements in the sidebar take up more space than is available, a scrollbar appears. The scrollbar scrolls correctly if you drag the slider up and down, or if you use the mouse scroll wheel to move up and down. The scrollbar doesnt scroll correctly when you click in the empty space between the scrollbar arrows and the slider. It moves at 1 pixel per click.

I am setting bug status NEW and o/s Windows.  Jay, is it other than an
accident that you reported o/s All?  I do not see the slowdown in the
daily dbgutil bibisect repository.

Setting o/s back to All.  I can't imagine what I was thinking.

Thanks Terry for noticing this, as this also scrolls by 1 pixel.

The Properties pane in Impress is similarly afflicted with slow
Comment 5 Matthew Millar 2015-04-17 13:07:05 UTC
Fault still exists in, however I'm only experiencing the speed issue in the 'Properties' tab of the sidebar.

Whilst there are scrollbars in all except the 'Styles and Formatting' tab, 'Properties' is the only tab with a scrollbar for the actual bar (due to the content exceeding the bar); all others are scrollbars within objects, e.g. lists with items which exceed the list object's capacity, but with the list object filling and not exceeding the bar.
Comment 6 Terrence Enger 2015-05-29 02:12:51 UTC
And I see the problem continues on Vista in daily build 2015-05-28.
However, I do not see the problem in (chroot environmet to) debian-sid
with daily dbgutil bibisect version 2015-05-28.

@Bjoern: As you stated that you fixed scrollwheel in sidebar, any possibility to see what is wrong here.

This seems to be about the deck are of the sidebar, not about the TabBar area.

Still an issue - small changes (SB_LINEUP/SB_LINEDOWN) have the same effect as large scale (SB_PAGEUP/SB_PAGEDOWN) [1]. EASYHACK?

Removing keyword 'needsDevEval' as this bug is an easyHack

Dear Yousuf Philips (jay) (retired),

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: https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

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

Warm Regards,
QA Team
