I received my Turret for Xbox One yesterday (for use with Windows 10), and I'm happy with the hardware (I particularly like that the mouse tray can be left at just the width of the mouse for putting it down - a thoughtful touch). Unfortunately, just one day in and the Chroma lighting on both keyboard and mouse has gone very wrong. It seems to be stuck on Spectrum Cycling mode, and even worse is that when I have Synapse 3 open it fights the selected lighting profile, causing flickering on top of being stuck on cycling. Results are different depending on profile, but what is happening is that Synapse takes control when it updates the lighting, but any gap longer than half a second or so, and Spectrum Cycling will take over, then back and forth like that. The final 2 profiles, Wave and Wheel, work as intended, I guess because they're continually updating, so the ghost Spectrum Cycling doesn't get a look in. But I'm not exactly going to use those profiles am I. Starlight comes close to working - I get usual behaviour, excpet that every so often a key will come on for a split second, and then sometimes I'll see the Cycling coming through. Static mostly lets the Cycling get on with it, except most times I hit a key it'll return to the colour I selected, and there's flickering intermitently. I've tried: Uninstalling all Razer software (4 times so far) Reinstalling with the same user account Reinstalling with a fresh user account Installing Synapse 2 (which can't see the Turret XB1 hardware) Setting new profiles, deleting profiles Using Chroma Studio (outcome is the same as using any other lighting profile) For the time being I've switched off lighting on the mouse, and turned brightness down very low for the keyboard, as I can't see what I'm doing with no lighting. Thanks the gods these settings persist, at least. I then exit Synapse and just have to live with the Spectrum Cycling (which I'm afraid to say I hate, I just want a static colour for general use).
