The 16bpp gray format does have known bugs. It was never supposed to have
been included in the framework but sneaked in there by mistake (or so I was
told by someone at MS)
Choose another format.

But I have always crash during rendering, but it works for 32bppArgb. It seems to me it is a bug in the FrameWork. I included the example of the code.
