Bug Description
watching video with mplayer/
artifacts show up on the screen. this started with switching to the new xorg
xserver.
it is not related to the drm module(i915), it happens both with and without it.
the problem can be triggert reliably by toggeling fullscreen mode on and off.
once that started there will also be pink artifacts in the video window, containing
parts of the gnome-terminal text or other areas of the screen.
