Skyward Sword Issue with Slingshot Cursor Disappearing

[Keoft]

I'm playing through Skyward Sword on dolphin and have just obtained the slingshot. However, when I move the aiming cursor it and the rest of the hud disappear behind the trees and continually pop back and forth between the front and back of the screen. This will almost make the game unplayable for me even though everything else runs great. How do I fix this?

Here is a screenshot:
