Just a note: all the "pixels" I got recently work flawlessly with 3.3v controllers. No diode to drop the supply voltage, no nothing
Tried running these with MDBT42Q module and ESPs. Powered the LEDs from USB -> 4.9V at the output of the LEDs. And a full strip with a proper 5V power supply that outputs ~5.0-5.1V, all worked without any problems.
And all of them are GRB or GRBW.
Maybe someone on the far east created a "compatible" chip that works reliably with 3.3v?
