Just noticed the 'spectrum analyzer' portion of the main window is ahead of the music by something like 600 milliseconds. Happens the same despite what skin I select. MP3, FLAC, no different.
Unsure if matter is corrected as of 1.2.0, I'm Ubuntu and 1.0.5 is all I get with default repos.
Try latest version from ppa: https://launchpad.net/~forkotov02/+archive/ubuntu/ppa
Analyzer seems good with the ppa version.
