but it takes forever with GTK3, so it might be, it's slow when using

--- Comment #17 from QA Administrators  ---
Dear Tor24_1975314,

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 #16 from Michael Meeks  ---
Priority-wise, the real question is if any hackers want to spend more time
trying to fix it =) there is no real way to encourage volunteers to do that by
prioritizing it differently. The best way to affect change here is to eg. add
some SAL_DEBUGs in the code there to print out what is going on, and/or try to
work out what is going on - why do we adjust the heights here ? do we do that
repeatedly ? what rows are being measured ? is there some way of significantly
optimizing this by looking at spans instead of individual rows etc. etc. anyone
can do that work - if almost any semi-technical person can spend a few days on
it they should make progress. Getting a good bisection would also help. Noel's
commit description doesn't seem to match the callgrind trace.

--- Comment #15 from Shane  ---
I challenge whether this is truly of low importance and minor significance.
Perhaps it is because not too many people use complex macros? But for people
using any significant macros this represents a substantial obstacle to moving
to LibreOffice.

In my case I am trying to move to LibreOffice from OpenOffice but it has made
some of my automation unviable. If MS Office performance figures are so many
orders of magnitude better then one can only imagine it could also present a
major hurdle to uptake of LibreOffice for some MS Office users too.

If we know that a flood of GetOptimalHeightsInColumn calls seem to be the
culprit here is there any kind of workaround to improve scrolling speed in a
macro? 

I have tried 

ThisComponent.LockControllers
ThisComponent.addActionLock()

and

ThisComponent.CurrentController.Frame.ContainerWindow.setEnable(False)

and, without timing anything too accurately, none of these seem to have
improved performance of my macro at all - it always takes an unacceptably long
time in LibreOffice 5.4.3.2 compared to the same code running in OpenOffice
4.1.3 (which isn't fast but is tolerable)...

The intersection of bibisected ranges reported in c#3 and bug 107535
comment 3, is a single commit, 
https://cgit.freedesktop.org/libreoffice/core/commit/?id=bcc51fb2ebdf77a1cc089857775fd742085b45b6;>bcc51fb2
"add support for in-place style preview".  I am adding keyword
bisected, and adding Noel Power to cc.

Bug 107535 is marked a duplicate of this one, and from notes I made
before filing bug 107535:
(*) Bug 80064, though resolved INVALID for lack of interest, impressed
me as a "definite maybe" duplicate when I filed 107535.
(*) Bug 84475, in light of its comment 4, is a good candidate.
(*) Bug 104802 is really close.
In light of these, I am raising the priority here to normal.

Terrence suspects bug 107535 is a duplicate of this. I did a callgrind of the

Created attachment 125937
  --> https://bugs.documentfoundation.org/attachment.cgi?id=125937=edit
profile result ...

I guess that ~all of the problem here is the 30k GetOptimalHeightsInColumn
calls which turns into 30 million separate GetOptimalHeight calls ... which
looks like a madness.

Surely we can iterate down the col/row tree and fetch the data more simply.

It is unclear why UpdateSelectionArea ends up doing a SetOptimalHeight anyway -
seems odd to me; ~all of the cost here comes from: the 'SelectionChanged' event
handling, which in turn comes from the VBA Range's "Select" method.

Hope that helps anyone wanting to have a poke at this.

ATB.

Hello,

with newer versions of LibreOffice the scroll down performance was improved but
is still significantly worse compared to MS Office which needs with option
"Application.ScreenUpdating = False" only around 1 second for the same test!
(Option "Application.ScreenUpdating = False" still does not works in
LibreOffice, see also Bug 52603)
This performance difference makes it really hard and frustrating to migrate MS
Office macros to LibreOffice to support migration projects and switching from
MS Office to LibreOffice.

Needed time to scroll down through 10.000 cells via test macro:

LibreOffice 4.4.5.2: 01:05 [mm:ss]
LibreOffice 4.4.7.2: 01:05 [mm:ss]

LibreOffice 5.0.2.2: 00:21 [mm:ss]
LibreOffice 5.0.3.2: 00:21 [mm:ss] 
LibreOffice 5.0.4.2: 00:21 [mm:ss]
LibreOffice 5.1.0.3: 00:25 [mm:ss]
LibreOffice 5.1.1.3: 00:25 [mm:ss]

(Test system: Windows 7 64-bit, Intel Core2Duo P8700 2.53 Ghz, 4 GB RAM, Java
SE Runtime Environment build 1.6.0_24-b07)

Needed time with Excel:
Excel 2010 with "Application.ScreenUpdating = False": ~00:01 [mm:ss]
Excel 2010 with "Application.ScreenUpdating = True" :  00:05 [mm:ss]

Can't bisect this any further - it doesn't take enough seconds for me to get a
reliable reading on speed (0:10-0:18 from the bibisected range through to
4.4.0.2, varying a couple of seconds at random)

In any case, if there is a current issue then it's more a job for
valgrind/cachegrind

One additional note - running the attached micro-benchmark on a dbgutil build
(e.g. 4.5 bibisect) is an order of magnitude or two slower, so make sure not to
mix types of build when comparing speed using it

That was a nightmare to bibisect - anyways
Ubuntu 14.04


Prioritizing:
Minor - can slow down high quality work but will not prevent it (by definition
this is about making things slower)
Low - with one test case hardly a high bug. Despite this being a regression as
of now it's affecting exactly 1 user.

My best time in bibisect package was 22 seconds so that was my base time. One
hit 23 seconds and I said that was fine. Most the other ones hovered between 45
seconds to 1:45.

add support for in-place style preview

selecting a style in the styles dialog ( without double clicking )
will apply the style to the currently selected cell(s) You can
with the keys navigate to other styles and they in turn will
also be applied. Preview will end when you click back onto the
document.

*FIXME* - the styles dialog isn't really suitable for previewing, a
new dialog ( possibly in the toolbar ) might be nicer ( see Excel )

*FIXME* - when there is a multiple selection the highlight colour
(applied as a transparent overlay) is most annoying ( and is mixed
with any background colour applied if part of a style )
see ( ScGridWindow::UpdateSelectionOverlay() ) However my puny
attempts to make the selection use a transparent colour made all the
borders of the selected cells dissappear. I guess maybe a box/border
 around each selected cell ( or group of cells ) would also work
but I didn't try that
