As seen in the attached stream the last line (probably last 512 pixel ?) of the lower line of the movie is always black. A similar issue I've with kaffeine (furthermore there I've another issue that the 1st 2/3 of the 1st line is blinking) therefore I assume that this is rather kernel than X11/KDE related, isn't it ?
