When I drag xterm over the suspended mplayer window, artifacts from the xterm remain within the window in which mplayer puts the video during playback. Dragging the mplayer window over the xterm window does not have any effect other than (partially) hiding the xterm window. Which X setting controls which variant is being used? Thanks, Richard
