Background true problem with 3.6.0

[FreddyX078]

After updating to 3.6.0, there is a problem with the option background: true.
Had it running fine for months, but after the update, videos won't load most of the time. Sometimes they load after a couple of seconds/minutes/page refreshes.

Even strange: I have 4 streams/videos on one page, but when I change background: true to one of the video, all videos stops playing.

Going back to 3.5.2 and background: true is working again.

Maybe you will take a look? Thanks!
