Hi,
It may sound strange the issue i'm facing with. Many times, while rendering high loaded scenes, the result comes like the following images. I see only the bottom couple of line pixels are rendered when this happens. Also i have found a solution for this on my own. After i initiliaze render, i manually slide down to the bottom pixels in render window and wait there till the iterations start. Then, render starts correctly. Yeah sound weird. I wonder what may this problem be related to ?

What is your GPU, assuming you are rendering with the GPU? What driver version?
