The problem is that an application may update many different areas of a window, and not all of those areas are suitable for video compression. So in the end, your screen updates will arrive as a mixture of all sorts of codecs. The best way to visualize this is to enable paint debugging, see XPRA_OPENGL_PAINT_BOX=1 in this ticket: https://xpra.org/trac/ticket/760 Cheers, Antoine > I will be grateful if someone could explain this.
