Hmm, that's very, very strange. Never experienced that myself and haven't had anyone else report it....
I did 99% of my internal testing using the CUDA acceleration, so maybe it's a bug I never ran into because I didn't do that much testing in CPU mode, other than to confirm that it was working. I'll see if I can recreate the issue over here by sticking to CPU for a while...
Does this happen anytime you use Terrain Color? Or just in a particular scene? If you can post your scene perhaps it's a combination of the specific color layers that you're using that are causing the issue...
