Trouble with rendering in DaVinci 9

Hi all,
I have trouble with DaVinci 9 (full software version) with rendering output.
When I apply some LUT (also DaVinci build in) to the node it make some strange artefacts on the picture (as attachment) and on rendered files as well.

It's an OpenCL artifact in Lion. Solution is to upgrade to Mountain Lion. This only affects AMD/ATI GPU users.
