ANNOUNCEMENT: It seems the DMA method was broken by the last Esp8266 SDK. For some reason my bits didn't update when I moved to the latest Esp8266/Arduino; I forced cleaned up my environment and now I am seeing what others like @3DSasha was seeing. I am working on looking for a solution, but for now there are two possible work arounds. One, Increase the count of pixels passed into the contructor of neopixel by 50, but still only work with the original count. OR Two, use the Uart method.
