A little more inspection shows that the bottom and right cut offs are due to the translation to "Layer1" (cut offs are at page boundary before translation) while the top cut off is due to a mask being applied over a blurred object (cut off is at bounding box of masked object prior to blurring).
The attached file demonstrates the latter problem more clearly. The dashed line shows the bounding box of the masked object before blurring.
