The mailing list should send an email mentioning that your message is
in the queue and provides a deleted link to remove it, but it is often
ignored so maybe I'll need to improve the message. If you have any
suggestions I would like to know.

If you try to capture your whole desktop, and then add some offsets to
it (such as "-i :0.0+80,91") then it will go out of bounds causing the
particular error messages you encountered earlier.

Without your actual command I'm not sure what you mean exactly.

If you just want to capture the particular window that you probed with
"-geometry 641x625+0+60" translates to
"-video_size 641x625 -i :0.0+0,60" in ffmpegese.
