I used the newest version of CUE. (had the same issue on the previous version of CUE)
I tried creating a new profile, and that didn't work entirely. Still had the issue, but rarely.
I'm also using a Corsair Strafe RGB keyboard.
I tried the soft reset, didn't seem to work.
Then I tried to exit CUE, and that seems to have fixed the issue.
But, what's the point if we can't use the software made for the peripherals?
