When I first installed the latest version, no immediate change was apparent, but after allowing it to run minimized in the background for a while, a change was seen by restoring the window. The window was extremely wide reaching past the left and right borders of my screen. I was unable to make the window any more narrow, and a restart of Pithos has changed the width to something more normal but still a little wide. After a little examining, it appears that the problem originates from how Pithos displays the titles of songs, albums, and any other piece of information that can become exceedingly long that is related to the currently playing music. It is possible that I am mostly alone in this problem, because I listen to classical music. The names of classical music songs and some albums can be quite long. Pithos does not break up exceedingly long song and album titles into multiple lines. Instead it extends the window borders until the entire title of a song or album can be displayed. I will greatly appreciate the fixing of this problem and hope that it is not a difficult problem to handle.
Very wide window appeared even soon after startup, due to long song title. Letting the window be resized, and wrapping the song title text, would help fix this.
