Go with card if you can't guarantee placement of the window.
The "from" option renders the object into a new buffer set up just for
the snapshot, while the older "of" syntax grabs the object's rect from
the composite screen buffer.
LiveCode renders only the content region of a window but the window
itself is rendered by the OS, so it has no choice but to obtain that
image from the screen buffer.
