The MBP having both discrete and integrated graphic cards will do
automate graphics switching by default. When it switches from discrete to
integrated one, the current display ID of the built-in display will
change and this will cause screen capture stops.
So make screen capture of built-in display continuing even if its display
ID is changed.
