Description of the bug: Two slides in a song shows at the same time on Foldback.
How was your service impacted? Had to stop showing song lyrics on that song. Restarted EW. Switched next service to Alternate Output.
How was your preparation time impacted? -
Step by step instructions on how to reproduce the bug: 

Turn on Alpha Channel for Main Output in Options (maybe). Turn on Foldback. Create a schedule with several songs. Go Live. The song shows on Main Output and Foldback. Go through the slides. Go to the next song and go through the slides. And so on. Eventually two slides will show on top of each other on Foldback, but only the next slide shows on Main Output as it should.

Alternate Output does not have this problem. I use Main Output and Alpha Channel for streaming.
