Sorry, I should have mentioned the problem is with the latest
PowerPoint 2007 Beta 2 Technical Refresh.
Well, I can repro it here, not with black backgrounds but with blue. Go
figure.
I'm running in a virtual PC, and I'm having trouble getting a screen capture
of it running full screen (which is where you can see the white lines best).
I'll report it. Hopefully MS already knows about it.
