Weird window behaviour in settings

When you wanted to sync audio or subtitles in Kodi 16, the main settings windows would disappear and was replaced by a small window with just a slider. That way you could adjust the settings while watching the screen.

Now in Kodi 17 no more. I keep the large main window and above that is the slider window. Hard to sync audio that way ( or correct brightness or contrast).

Is there some setting I forgot to adjust ?
