All quite normal.

Cant say I have noticed before, but this makes sense. Maybe I have an issue with poor regulation of the supply then, as this seems excessive. I can go from out of lock one way, right through to out of lock the other way just by varying the brightness. This is definitely new as I do tend to alter the brightness often depending on ambient light in the room.
Certainly the Wavy picture is a new thing.
