You mean the Lutron Caseta ones right?
Yea I do notice the flickering in one of my rooms. They do sell a capacitor to solve the issue Lutron LUT-MLC https://a.co/d/eXWMCdY
I haven’t bothered with it since the room with the flickering is my server room.
There’s a new line of Caseta switches which actually look good and are traditional.
Can’t be bothered to replace mine and barely use them anyway. Just use HA and automations for the most part
