Bambu Lab A1 power fluctuation making my household lights flicker. Anyone else?

I recently bought a Bambu Lab A1, and whenever I start printing, my household lights start flickering in a rhythm.

I searched for this on ChatGPT and Gemini, and it seems to be a common issue in certain countries depending on the power grid. Apparently, the flickering happens because the heatbed heating process consumes power in a "breathing" pulse (PWM), which causes the voltage to fluctuate.

I am plugging the printer directly into the wall socket and not using any extension boards, but the flickering is still very noticeable.

Has anyone else faced this issue? Is there a permanent fix for it?
