Description pos 2013-03-13 20:00:02 UTC
Problem description:
When scrolling in a big document the document freezes for half a second after a few pages and then continues again. Then the pattern with a freeze repeats again and again if you do a continuous scroll.

4.0.1.2 release is not usable on MAC (have updated java, updated mountain lion). 4.0 beta had the same issue. So I continue with 3.6.5.2. 

Steps to reproduce:
1. ....
Use Libre Office writer 4.0.1.2 release and open  document with many pages (I have used 50-90 pages document with no advanced formatting)
2. ....
Scroll
3. ....

Current behavior:
? Se above

Expected behavior:
Smooth scrolling as in 3.6.5.2

Operating System: Mac OS X
Version: 4.0.1.2 release
Last worked in: 3.6.5.2 release

It seems it's getting much better when changing and raise the memory and cache settings. But looking at 3.6.5.2 where this is not a problem, the libre office writer settings for the cache and memory are the same as in 4.0.1.2.... ??????

Hi,

Thanks for reporting.

To reproduce this behavior it will be necessary to have an example file which you can reproduce this behavior with.

Just some other information: does the document contains "a lot" of elements for example: comments, images, footnotes,...?

Kind regards,
Joren

A feel is that 4.0.2.2 is better than 4.0.1.2. But still not as good as 3.6.5.2. 

As the document I am working on now (170 pages) is not public info I have to find/create some other documents to test and post if the same problem is in that. The 170 pages document is 5 MB in size and has today maybe 10 images (png and jpeg). Just a hand full of footnotes. But there are maybe 30-50 tables. Some quite big. Table of content index span over 5 pages.

But of course I can see where this is going. And I of course understand that it is hard to pinpoint such a problem with to little information.


So... I will look into it and se if I can do/find a fake doc with the same issues. But the problem c o u l d eventually be in many documents as I have only tried Libre office v 4+ on the work I am doing right now. Will do some checking....

Changing 'regression' -> 'PossibleRegression' until we have independent confirmation of a regression.

As of Libre Office writer 4.1.1.2 the problem is gone

Maybe no need to dig into this in an old release... Or?

There have been some problems fixed with the responsiveness in recent versions but I do find there is still a slight delay that occurs when scrolling using the mouse wheel.  It seems to me to be related to the headers and footers.  It seems like if the scrolling stops with the mouse cursor over one of these areas then the document stops responding for a short time. I'm not sure if that is exactly what's happening but it seems to be the issue.  The new way of doing headers & footers have caused other problems so maybe it's related.
