[FFmpeg-user] Problem with GDIGRAB device on Windows 7

Hello ffmpeg/gdigrab gurus!

We are using "gdigrab" device on Windows to share/stream video for a 
specific application window (identified by a title as "gdigrab" requires).
Everything works great on Window 8.x - actual application window (and 
not the region on the desktop occupied by the application window)
is getting shared and successfully played by the player on the receiving 
side. Which means that even if shared window is overlapped by the
other window on the source - still the application window is getting played.
Unfortunately, as we discovered, "gdigrab" doesn't work correctly on 
Window 7. And instead window sharing it actually does the region sharing.
Which pretty much means that if shared window is being overlapped by the 
other window on the desktop - that's what getting played on the
receiving side.
Just for reference - we tried to do window sharing with 
screen-capture-recorder and unfortunately got exactly the same results.

I would greatly appreciate any help/advise anybody can provide on the 
subject. And please let me know if there is any other information I can

Greatly appreciate your help
