            Bug ID: 114647
           Summary: Presentation: multiple animated gifs consumes CPU
                    causing hang
           Product: LibreOffice
           Version: 5.0 all versions
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: atoth at atoth.sote.hu

Description:
When multiple animated gifs are present on a slide, it causes impress to
consume CPU causing a hang in presentation mode. I experience the issue on
Windows 7 Pro/Enterprise 64bit, but not on Gentoo compiled from sources.

Steps to Reproduce:
1. Load a presentation with multiple animated gifs on a slide
2. Switch to presentation mode
3. Step to the slide

Actual Results:  
CPU usage goes high, libreoffice becomes unresponsive. Regular users may thing
the whole system went down, but switching tasks shows only libreoffice hanged.

Expected Results:
Libreoffice before version 5 and current Openoffice can present such a slide
without any problems or hickups.


Reproducible: Always


User Profile Reset: No
