Yeelight Bulbs very laggy

Hello, I recently bought 2 Yeelight Smart Led Bulb 1s to connect them with Razer Chroma. So I can connect the bulbs with Razer Synapse 3 and Razer Chroma Connector, but the problem is that the bulbs are very "laggy", not fluid at all, when I apply a wave effect. And another question is that the bulbs can't deal with the black color, is that normal or not ? Can someone find an answer to theses problemes ? Thank in advance.
