    I've got a 21k pixel (ws2811 square nodes) matrix with (2) MKII LR boards, in condensed mode. Each string is 500 pixels, zigzag @ 125.
    Last year I'd have a couple random pixels stay red at the end of a song, but would cleanup when next song began.
    This year there are more frequent, and in dark area of a video that plays, there is a red flicker throughout the dark area.
    I run at 50% intensity. Power injection @ multiple points on each string. (64 350w 12v power supplies)
    It's on a huge steel structure, 42' tall x 30' wide and I've assume it may be noise.

    any ideas?

    I've had random pixels stay red when voltage is too high. Lower psu output to 12.0v and red pixels went away.

    I think I set all of them to 12.20v with no load. I'll give that a shot today!
