X log

when playing an xvideo on sprite (eg mplayer -vo xv:port=104 ~/mnt/lin-ult/tools/Mplayer/videofolder/helloMoscow.mpg), if the video is dragged past the left hand edge of the screen then X dies (Fatal server error:sna_blt_fill_box:3326 assertion 'box->x1 >= 0' failed).

    sna/video: ValidateGC before use
    
    We required the GC->pCompositeClip in order to apply the current Drawable's
    clip to video region, this requires us to call ValidateGC first.
