            Bug ID: 135390
           Summary: Linked Graphic on localhost slows freezes application
                    for several seconds when not available
           Product: LibreOffice
           Version: 6.4.5.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
Linked Graphic on localhost slows freezes application for several seconds when
not available.

I was sent a file by someone else, linking multiple local web server images.
Scrolling through this document froze the application for multiple seconds, as
well as freezing other LibreOffice application instances.

I have a fairly high spec PC (32 thread, 64GB ram) which was hardly under any
load. Perhaps the resolving of this linked graphic can be done asynchronously
to prevent blocking the user.

Steps to Reproduce:
1. Insert > Image
2. Enter Localhost image URL as 'File Name' and check the 'Link' checkbox >
confirm 'Keep Link'
3. Save and close document
4. Stop localhost server
5. Re-open document, scrolling over the localhost linked graphic will freeze
Writer for several seconds. It also freezes other open LibreOffice Writer or
Calc instances.

Actual Results:
Scrolling over the localhost linked graphic will freeze Writer for several
seconds. It also freezes other open LibreOffice Writer or Calc instances.

Expected Results:
No delay, should just be an unresolved graphic without blocking the application


Reproducible: Always


User Profile Reset: No
