Weird Texture/Alpha issue with Foliage

This video shows the problem. It’s like the alpha channel is slipping or something. Maybe the shadows. I honestly can’t tell. Any help with this would be awesome. I know these forums are a bit “lean” on help but I really hope someone out there has seen this. I’ve been banging my head on this for sometime and I’m at my wits end. If I can’t figure it out soon I’ll have to go and render in Redshift, and (PUKE) I don’t want to do that.

Thanks for any help!

Have you tried reducing the ambient occlusion ( in the material )?
