Good evening everyone, I apologize in advance for replying to a 2 year old post. Today while using clementine I "solved" the problem of the giant icon in the notification area. Just play a song and move the playback slider back and forth and the icon will automatically resize to the correct size. Obviously you have to do the procedure out every time clementine is opened. It is not a solution to the problem but a way around it. I thought you were interested in knowing.
