Comment (by LordHDL):

 Not quite sure what you mean?  I've tried many versions including the
 latest snapshot posted there.  Refer to the images and videos I linked to
 above.  Cropping is done incorrectly in as you can see a tiny bit of my
 desktop (to the left) as well as a bit of the window's title bar at the
 top.  If I change the offset by one pixel, you'll see a bit of desktop on
 the right and bottom edges instead.

 This doesn't seem to be present with Windows screen capture, as I asked a
 friend of mine to test it and his video was cropped correctly.
