Sam, I found out similar issues also when starting slideshow with slide that contains video directly (shift + F5). This issue is not present if i start slideshow with first slide. I also noticed if the video is not entirely inside slide - the video acts weirdly when in presentation.
However this is not the same issue as I reported. New bug should be opened. One should test if this issue is persistant with libreoffice- gtk2 (gtk3 removed) and also without any gtk2 or gtk3. Also test on other linux distros and/or Windows.
