            Bug ID: 122952
           Summary: Writer typing lag when editing text while image is
                    showing on screen
           Product: LibreOffice
           Version: 6.0.7.3 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: emoape at gmail.com

Description:
When editing the text in a Writer document there is a very noticable and
annoying lag when typing if there is an image in the document header showing.
When the image is not in sight (it is in the document header but not on the
screen) the lag is gone. Could it be that Writer redraws the image(s) with
every keystroke?

Steps to Reproduce:
1.Start a document, open the header and insert an image (e.g. a .png)
2.Start typing text in the body of the document with the header image in sight
3.Delete some text
4.Insert so mucht text that it becomes possible to scrol the header image out
of the screen
5. Edit the body text with the header image not visible on the screen

Actual Results:
When the header image is visible, editing body text is lagging (a lot). When
the header image is nog visible the is nog (noticable) lag.

Expected Results:
The should be no lag in both situations


Reproducible: Always


User Profile Reset: Yes
