That's not what I had in mind. To copy an overlaping area you simply copy the entire area to off-screen video-memory. Then copy it from that off-screen memory to the final destination in the frame buffer.
I tried that, but got very strange behavior that I can't explain. If you were to say move a window to the right, the desktop background would fill in in the exposed area, but the the window contents wouldn't show up in the newly covered area. The same thing happened to the temp copy. Alex -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
