Comment (by DiJuMx):

 Yes, I just tried it, and it doesn't appear static. Could you try with the
 offset, so:

 {{{
 ffmpeg -f x11grab -show_region 1 -i :0.0+50+50 -qscale 2 out.avi
 }}}

 If the top-left corner of the capture region is "+x+y", the ''non-static''
 portion of the capture seems to start at "+(2*x)+(2*y)"
