Fullscreen on wrong monitor

Use a setup with at least two monitors and configure a single desktop that spans across all displays. Open a video in fullscreen on the second display that has a higher resolution than the display. Then you will see that the video is opened in fullscreen on the first display. Without the fullscreen mode, the video with the higher resolution will overlap from second display into the first display. This seems to be the reason for displaying the video on the wrong display.

This command will show the video on the wrong display:

$ mplayer -xineramascreen 2 -fs <video file>

This command will show the video on the correct display:

$ mplayer -xineramascreen 2 -fs -xy 0.1 <video file>
