That is normal for the QuNexus. The LEDs are addressed in a matrix, and because they're white and blue the 3.3v control lines can't close the 5v drive lines quite fast enough, so sometimes the next LED in the matrix gets a few unwanted electrons. It's a tradeoff between the resolution of brightness control and the ability to get rid of bleed. The result is what we hope is a reasonable medium as it's not visible under most conditions, and the led feedback is fairly responsive, but it is frustrating that it's not perfect under all lighting conditions.
