Yeah, those panels are quite delicate, so they need a "maintainence" waveform(full refresh/flashing) for every now and then, to wiggle those stuck droplets.

Also when pushing for high refresh rate, you may need to use higher voltage, to make the droplets rise/fall faster. But sometime, those droplets are driven too hard and kind of stuck forever, so yeah, that's a trade off.
