           Summary: Animated Gif's Cause Libreoffice Impress to Hang /
                    Crash / Become Very Unstable Under Windows 7 / 10
           Product: LibreOffice
           Version: 6.1.0.3 release
          Hardware: All
                OS: Windows (All)

          Severity: normal
          Priority: medium

Description:
Animated Gif's are causing Libreoffice to crash / hang / become very unstable
on Windows 10. The version of Libreoffice being used is 6.1.0.3 (the latest
from the donwload site. 

Basically some animated gifs work, some animated gifs do not work when being
uploaded into an Impress presentation. The files are fine (they work in
Powerpoint and other programs). They display and animate a bit but then the
program will hang and really slow down (mouse cursor animation changes / real
lag in the program) for example. 

Not all animated gifs that I download from the web cause this problem in
Impress but many do. 

Not sure what causes it but it's a pretty basic thing that needs to be fixed.

Tried on many PC's at our school in China - problems persist. 



Steps to Reproduce:
1. Open Libreoffice Impress. 
2. Try opening the animated gif files provided. 
3. Impress should hang / slow down / become unrepsonsive. 

Actual Results:
Libreoffice Impress becomes unstable and doesn't work or function properly. 

Expected Results:
Libreoffice will become unstable and hang and crash. 

Animated gif files should display properly and not cause Impress to crash -
this is a pretty basic thing and a severe bug which hopefully will get fixed. 



Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:

Sometimes when moving the mouse cursor over the animated gifs the hang / slow
down occurs more.
