Comment (by rivierakid):

 I have created 16-bit TIF from 8-bit (test16.tif in attachment) and it
 works, no artifacts!!!
 So I think that the conversion from 8-bit RGB to k422YpCbCr10CodecType is
 buggy. Your theory is probably right except that JPEG can't have the Apple
 YUV 10 bit space, yuv422p != yuv422p10. So JPEG encoding test is
