<pre>Description:
When I have an animated gif "video" in an Impress presentation, then this
animation is properly displayed during the edit mode of the slide show. But
when starting the slide show (e.g. with F5) in presentation mode, then this
animation is not shown at all. This only happens with (animated gif) videos
that contain an "alpha" transparency.
Steps to Reproduce:
1. add an animation (animated gif) with transparency to an impress slide show.
2. (the animation is displayed fine during this edit mode)
3. start the presentation, e.g. with F5
Actual Results:
The animation is NOT visible on the presentation screen.
Expected Results:
The animation should be visible on the presentation screen.
Reproducible: Always
User Profile Reset: No
Additional Info:
* I have observed this under Windows as well as under Linux.
* When I remove the transparency from the animated gif file, then it works fine
in Impress.
* This happens with hardware accelaration ON, and OFF in the LibreOffice
graphics settings.
* I will attach a sample odp file that can simply be opened to show the
described behavior.</pre>
