New lens effects bug on animation

I’m rendering an animation with the new lens effects. I’m saving them as a render element, and every 10 frames or so, i have this glitch happening all the time. Even with a simple scene, just turning the lens effects on, in animation it’s still happening. Right now i’m roto’ing it in nuke, but ideally this shouldn’t happen.
I’m not using any filtering or obstacle image.

I exposed this problem a while back and nobody answered. lens flares problem - Issues - Chaos Forum
On my las animation, I had to mask the layer too.

bump… anything?
