Dear bmklampe,

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

--- Comment #14 from Buovjaga  ---
I bibisected on Linux with 43all for the horizontal scroll in werte sheet and
it blamed this range:
https://cgit.freedesktop.org/libreoffice/core/log/?qt=range=18e6e7d929c2be209407ed2e56b8ec4d5e6c4900...9ca02a663c3eee2698eb360dd5dc7afb1951e743

It was a bit challenging because the difference of CPU hammering is not very
big.

Guessing, the reason could be
https://cgit.freedesktop.org/libreoffice/core/commit/?id=435c117c1c684d4603f557ed821c1fd5ee057086

parent  904763b1134bdd84a4e64de1e037da5cac192f27 (diff)
some optimization of ScAttrArray::GetLastVisibleAttr()
Method assumed that not much attribution happens below data and started from
the end of attribution, in the case of not much attribution it worked fine.
For the case of many differently formatted areas with a sufficiently large
area of visibly equal attribution near data end it was a bottle neck looping
over unnecessarily many comparisons. Start at data end instead. For the case
of not much attribution it doesn't really matter, and for the case of no
sufficiently large area below data end it doesn't matter at all and compares
the same number of entries. The drawback would be a large area near
attribution end with many small areas between data end and the large area.

Observed with test case of fdo#46160

Buovjaga: Would you mind to test if this is really Win only? Bibisecting on
Windows looks nearly impossible. Windows Bibisect repositories go back to 4.3
if I understand correctly

I see performance regression with the attachment in 5.3 daily build / Windows
7. 

Opening the spreadsheet takes ~45s (about twice as much as with 5.2.3.3), and
scrolling the chart screen is sluggish, while it wasn't so before.

Scrolling is a bit slow as is copy row 52 from column A to BV, but no
crash.
