Hi Radiomanoff
The static display is a symptom of installing the current version of mpd_oled (with the change to the mpd_oled service) over any previous version of mpd_oled. If this is the case, then you should be able to fix it by running the commands from the issue I linked to
MPD_oled over MoOde audio rel 8.3.2 · Issue #84 · antiprism/mpd_oled · GitHub
[EDIT: but use your mpd_oled options in the final command]
Adrian.
