Apologies for not being able to reduce this any further, but it seems like this bug is very timing dependent. I remove any elements from this .love, the bug doesn't occur.
Basically -- I have a list of long sounds being played via streaming, one at a time. While these sounds are playing, I'm playing both one-off sounds and sounds that loop for a bit. The attached .love demonstrates this. When the third song plays, it starts stuttering on the first second or so of the song.
Some things I tried to focus in on the bug, but "fixed" it:
- Removing either the one-off or the looping sounds
- Using shorter songs
- Using a single song, or a single looping sound
I tried on both Windows 7 and OS X 10.8 and this bug seems to happen consistently with the .love.
