Videoclip playback during full-screen presentation has very noticeable
flickering in the area of the videoclip.

Steps to Reproduce:
1.Include this MPEG4 videoclip in a slide
https://www.dropbox.com/s/co6frgbaxaisdmi/Crossfade.m4v?dl=0

2.Play the presentation full screen


Actual Results:  
The videoclip will play but the image within the area of the videoclip has
clear flickering instead of a smooth crossfade transition among frames.

Expected Results:

Additional Info:
The video plays without flickering if played during edit mode of the slide, or
with libreoffice's internal player.

The bug happens only when presenting in fullscreen mode.
