Does iCue revert to onboard settings on Win10 lock?

I'm new to my K65 keyboard. Loving it, but just noticed that when I lock my desktop (Win-L), the currently active (even if the default) profile is replaced by my onboard profile, which is also what happens when iCue goes south. (I notice it because of the change in keyboard lighting.)

That it happens when iCue crashes I understand (though there's something to be said for a $30 Redragon K552 that keeps everything onboard), but it's happening upon LockWorkStation(). Is this expected behaviour?

(P.S. Is Corsair interested in iCue crashes? It periodically faults in Qt5Gui.dll, and I'm getting WER dumps.)

Thanks for any input.
