Graphics glitches on iPad Air

I'm using the latest version of Unity and running up against some camera issues on iPad Air (the project displays fine on all other iPads).

Problems:

After a new scene has loaded (loading entirely, not using LoadLevelAdditive) graphics from the previous scene are still visible in the background.

Objects are leaving ghosting / trails behind them, even though the camera is set to clear / depth only. Normally, this happens when camera is set to 'don't clear'.

Has anyone else...
