Is anyone else having motion background issues with current version? This is first time I've had this issue, so I don't know if it was a glitch that a reboot would take care of, or something wrong with the latest update.
Song slides with motion background was giving me problems this morning. They would show on one slide, and then every couple slides, the words would come up, but have a black background (instead of motion graphic), then after 10 seconds or so, the motion graphic would pop back on behind the words. Occasionally the motion background would show, but it would be 'frozen' like a still background for some time before the motion animation would play.
These issues were on 'Song' items, where a single motion background was added from the media library behind song lyrics. So the issues were occuring within a set of the same item group. The problem happened with 3 songs that I had different motion backgrounds on. The motion backgrounds were from the Media Library, not custom uploads. The one song where I had a static image as the background did not have any problem, and did not black-out from slide to slide.
Again, this is the first I've ran into the issue. Will have to wait until next week to see if it's recurring. I couldn't reboot the machine to see if restarting windows would fix the issue, as we were in the middle of live service.
