There are 2 related issues with the colour wheel in Mac. I'm using a Late 2013 MacBook Pro.
1. Clicking on the pointer in the colour wheel causes the pointer to jump. In the video provided below, you can see the mouse cursor clicking directly on the pointer, however, the pointer automatically moves up each time.
2. Clicking on the colour wheel triggers the notes in the background to play. In the video provided below, you can see the notes flickering when moving the pointer around in the colour wheel. The screen recording didn't record audio otherwise you would also be able to hear the notes. The notes should change colour when using the colour wheel without them being triggered to play.
Interesting. Your method resolved the issue. I will just go full screen through the application. Thanks for the suggestion!
