Phantom trails

[Scott Christie]

This is something I've reported in emails but not specifically a bug. There are phantom trail lines that show up that when you move the view they do not respond like the real trails. I was hoping this would be fixed because they distort my script when played.

Is this bug still valid? I cannot reproduce it.

Apparently you fixed it already (issue with projections)
