I doubt, rather LCD data line from i2c adapter bad solder.
You can check by disconnecting SSD, if still persist.

So checked with my pwm regulator screen next to SSR. Goes grazy as well.

How close is "next" ?
I have 10 cm between the controller breadboard and dimmer board PCB, and no influence.

Like physically couldn't place closer for test. But tc4+ lcd 6cm away gets affected.
