Question I'm having performance issues when on the Radar tab in Final Cut Pro X - what's going on

In Final Cut Pro you can experience performance issues when you work while the Radar tab is displayed. We recommend to close the LM2 / LM6 UI while working in FCPX; LM2 / LM6 will do the measurements even while closed and you can always call up the UI to get the program loudness descriptor figures or check the radar.
