The same video every screen setting is checked, but the app often plays different videos on each screen.

To Reproduce
Steps to reproduce the behavior:

1. Make sure the right setting is made (to play the same video on all screens)
2. Click on 'preview', or wait for the screensaver to launch
3. Notice that different videos are played.

Expected behavior
When I make that setting, I expect the same video to be played on both screens.

Aerial Version
Beta 0.5.3

Additional context
It doesn't happen all the time. Sometimes the same video is played.

I recorded a video with my phone to show the behavior.
