I’m in the same boat, w.r.t the “pulsating” lights at low brightness levels - I wouldnt call it flickering, but getting slightly brighter/dimmer over the course of ~1s. This is with a single switch (so presumably trailing edge now), with 8 lights on the circuit. I increased the frequency of power reports from HA, you can see that it’s stable for a bit, then starts fluctuating, corresponding with the unexpected changes in brightness
