@FaustoGSR With skin Estuary you have to change one line in file /usr/share/kodi/addons/skin.estuary/xml/DialogSeekBar.xml
:
<visible>Player.Seeking | Player.DisplayAfterSeek + !System.IdleTime(5) | [Player.Paused + !System.IdleTime(5) + !Player.Caching] | Player.Forwarding | Player.Rewinding | Player.ShowInfo | Window.IsActive(fullscreeninfo) | Window
.IsActive(videoosd) | Window.IsActive(musicosd) | Window.IsActive(playerprocessinfo) | !IsEmpty(Player.SeekNumeric)</visible>
