Description Dmitry 2018-04-14 15:56:08 UTC
LibreOffice Impress and LibreOffice Draw freezes after adding of some kinds of animated gif. And then it works fine for a while and then again. The issue appears when the page or slide with the gif is shown on screen.
Some kinds of gifs works as expected.
When demonstration runs (F5) freezings does not appear.
Probably turning off of gif animation in edit mode could temporary solve this problem.

Steps to Reproduce:
1. Create a new presentation or drawing.
2. Insert a gif like the attached one.
3. Wait a little and/or right click on the gif.

Actual Results:  
It freezes for 5-30 seconds then works, then freezes, then works and so on.

Expected Results:
It should work without freezings

Reproducible: Always

User Profile Reset: Yes

Probably any of big gifs is the cause.

I guess it is the same issue than bug 98500.

Best regards. JBF

I think I should say that the difference between this bug and bug #104878 is in CPU usage. My CPU usage is ~33% when LO hungs up. I have amd 250 CPU, 2 cores, 3GHz. Probably it's not a duplicate. 

This issue is present on LO too.
