Hi Michael, yes, I thought it is this reason. I read about som kind of "bypassing" video buffer but no idea how this can be done. :(

I remember this pheonomena back from when I was doing DirectX/DirectShow development. That black rectangle where you had a video playing is a special region of the screen that allows YUV data to pass through the video buffer. In other words, they make all the RGB pixels 0,0,0 and overlay a YUV video through that black "hole". So there's nothing you can capture there.

Hello,

I wondered if this is possible with pygame - I would like to take screenshot of my desktop. It means, my pygame app should run in background and be able to take whole screenshot of any application/whole desktop (not just itself), even in fullscreen mode (of in opengl, directx, direct3d, sdl mode).

Because I tried to achieve this with python GTK but app for example when I took screenshot of my desktop and some video player with direct3d were running, I got black rectangle in that screen position.

Is there any sample code for this please?

Many thanks
