From SilentExcept words:

"problem is if the plugin sets this #Play.Current.Thumb property (like tvseries or moving pictures or trailers or ...), then when you exit the fullscreenvideo (with x or esc), then SetCurrentFile is called and SetCurrentFile clears most of the plugin set properties so next time you press x and view osd everything will be cleared.."
