I cant fix it, my razer mouse 1 week old, I selected Spectrum Cycle as my effect after like 3 cycle the color will freeze. tried both synapse 2 and 3(currently using synapse 3) and still the same updated to the latest version. also tried deleting all profiles and clean install still the same after and after. I tried to end task the LEDKeeper and it works but only for a moment like 3 cycles again and freezes. I think it is software fault more than just hardware. using windows 10 64bit updated to latest. oh by the way here is the video footage. Thanks, Pls it is my first ever razer product and I order Blackwidow Chroma v2 I don't want to get disappointed.
