Darkness bleeds when moving the head with the Rift

Hi everyone,

Has anyone else gotten the weird bleed of darkness/shadows when using the Oculus Rift?

When the scene is well lit, everything is fine, but when the sun is turned off and there is a lot of darkess, only when my move my head (with the oculus rift) the darkness bleeds it is as if all the geometry is rerendered as I move my hear but the shadows take a little longer… its like a dark purple blurring effect.

I also noticed that if I move the character around it doesnt happen, its only when I turn my head around.
Anyone else have had this… thing? Why does it occur?

Any advice is welcomed!

thanks in advaced,

Seichi
