Nozzle LEDs flickering if set to white + logo LED effect
I am currently using a Xol toolhead and wired the LED harness as per their instructions. It uses 1x WS2812B 5050 and 2 WS2812B 3535 (small RGB LED sequins). It works with your typical (static) stealthburner cfg. But since I am using LED effect, there is an issue such that if the logo LED has an LED effect and I set the nozzle LEDs to white, they begin flickering, But if both the nozzle and logo LEDs have an LED effect, they work just fine. I have made a few observations while troubleshooting. I've redid my harness like 5 times as I initially thought there was a loose wire touching something, but each time has been the same effect. Another thing I did notice is that if I set the framerate of the logo LED to something high, the white nozzle LEDs flicker faster, and if I set framerate lower like 2, it flickers slower. This only happens if nozzle LEDs are set to white (ie red=1 green=1 blue=1) . It does not flicker if I have a logo effect and set the nozzle to a single color (R/G/B), but the moment I introduce another color, it flickers. I've also tried virtual_leds as well as putting a 470ohm resistor and it still doesn't work. Both the 5050 LED and 3535 LEDs are GRB color order.
Maybe this is just a hardware issue (ie the small RGB sequins aren't compatible with LED effect?) but it doesn't make sense why nozzle + logo both with LED effect works fine, but nozzle with white and any logo effect doesn't work. I have since changed my cfg to only have white nozzle LEDs while printing, with a static logo LED but I'm hoping a brighter mind can figure this out.
Update (same day): My tests thus far were without any extruding. Now I am having the same issue when extruding while both nozzle and logo have an LED effect. I did recently switch to a LDO Nitehawk 36, perhaps this is the issue? I never tried this LED harness when I had the EBB36 though so I have no point of reference here.
[neopixel sb_leds]

# The pin connected to the neopixel. This parameter must be provided.
chain_count: 3
# The number of Neopixel chips that are "daisy chained" to the
# provided pin. The default is 1 (which indicates only a single
# Neopixel is connected to the pin).
color_order: GRB
# Set the pixel order required by the LED hardware. Options are GRB,
# RGB, GRBW, or RGBW. The default is GRB.
initial_RED: 0
initial_GREEN: 0
initial_BLUE: 0
# Sets the initial LED color of the Neopixel. Each value should be
# between 0.0 and 1.0. The WHITE option is only available on RGBW
# LEDs. The default for each color is 0.#
