CGDisplayCapture and display sleep

[Christopher Hunt]

Hi there,

Can anyone confirm that CGDisplayCapture prevents a display from  
sleeping? I'm guessing that this is the case as I'm entering full  
screen mode (full screen gl context) and my "pmset -a force  
displaysleep 1" doesn't work when I'm in fullscreen mode.  
Additionally using the sys prefs UI to sleep the display after 1 min  
of inactivity doesn't appear to work either. All is fine if I'm not  
in full screen mode.

Thanks in advance.

Kind regards,
Christopher
