Description: In preferences in section "Cover art" in the field "Path to MPD music root:" I register a way /home/xandry/Music/, I stick to "Close". The disk cover is displayed. After transition to the following composition under the list (from this an album with the same cover) the cover is not displayed any more. I look in options - "Path to MPD music root:" it is again empty. Tick "Show album cover art" remains on a place. All other options remain normally.
