I recently updated to iCue 4 and can't turn off the defective LEDs.
I have a K70 LUX which has 5 keys whose LEDs malfunction. They glimmer/twinkle with the default red color really fast when the keyboard is powered up and then end up being permanently red and slightly dimmer than the other keys after a few seconds. Using any color from iCue resulted in that color mixed with the red.
In iCue 3 I was able to turn off those keys from the static color effect by deselecting them in the software and those key LEDs would turn off completely. But in iCue 4 deselecting them only turns off the static color chosen for the effect and the faint red color remains. I would very much prefer no lighting on those keys than a mix of the malfunctioning red and whatever color I choose.
