On all platforms, depending on the player, there may be problems if the video window is moved
between screens while video is running. It may be necessary to close and restart the video player.
Known issues - general
Don’t change the logged user or the display mode, position or arrangement of attached screens
while a video is running. This usually confuses the video player and the video may stop playing.
