            Bug ID: 120114
           Summary: Very slow document rendering - black screen and UI
                    freezes
           Product: LibreOffice
           Version: 6.1.2.1 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: tomasz.palutkiewicz at gmail.com

I have one very large document (over 100 A4 pages, 4MB of xml content)
with multiple complex tables, graphs, images, paragraphs, comments...

I cannot work with it at latest versions (6.1 releases)
as whole UI freezes almost all the time,
"(Not Responding)" appears in the window title
and black screen appears instead of document content.

It seems that too large portions of document are redrawn too often;
so the process is not finished until redrawing is started again.
It happens even at very simple pages with just few lines of text,
so probably it is related to the rest of the document.

I would recommend to add "JUST ONE PAGE" display mode,
which renders only the page at which cursor is currently located
and/or limit usual rendering to the 3 pages around the cursor or less
(it should be easy to first find 1 or 2 previous and next page breaks
and then process and display only part of document between them).
