Try putting a resistor from the Pi's gpio output to 3.3V, the 400 ohm resistor would do nicely, if not some value between 330 and 1k
There are at l;east two potential problems ...
The input spec for the ws2812B requires a higher voltage than the Pi provides (0.7 X LED-VCC = 3.85V)
When the Pi outputs two "ones" in a row, there can be a very slight spike in between (or maybe the other way around with Zero's).
