Severe flac playback issues
Playing FLAC files in version 2.1.1 under OSX (10.9) has major issues. Flaws reach from the player skipping parts of the audio, minor crackling in the background to stutter. This is not random, but can be repeated and always shows up at the same spots of the songs. The files themselves are find, they convert e.g. flawlessly and cleanly to MP3 by using FFMPEG or play on Android. I also played them without any problems on older VLC versions under Linux (don't recall the version used then though).
