            Bug ID: 143268
           Summary: Slow response in document with many tables
           Product: LibreOffice
           Version: 7.0.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: genericinet+libreoffice.org at gmail.com

I have a document that contains a large number of tables.  I've finally located
the cause for a severe lag in the response of the document when scrolling or
editing.  Version 6 with this document works fine.  Version 7 has the lag.  I
haven't determined a specific version number where the problem began, but from
what I recall, I think it was with 7.0.0.  

In trying to determine what I could do that might improve the speed, I found
that enabling the Content Navigation View in the Navigator, with the cursor
outside of a table (so that the headings view remains displayed), immediately
caused the response to be as quick as the response on version 6.

I then discovered that because most of the editing is done in tables, the focus
in the Navigator will switch to the Tables navigation and the extreme lag
begins.  Version 6 does not change the focus from the Headings navigation even
if editing inside a table.

I then discovered that in the context menu when right-clicking on the Headings
entry provides an option to disable Outline Tracking.  Would it be possible
that such an option to disable Table Tracking for the Tables view would prevent
the focus from going to the Tables and thereby causing the lag as the program
tries to keep up? 

Content Navigation View can be enabled to only have the headings displayed in
the Navigator, but I do use the various other views also, such as sections and
comments, so I like have them all displayed.
