I've got an RPI4 8GB with the Adafruit RGB Matrix Bonnet hooked up to a new 3mm pitch 64x64 panel and I'm seeing some "random" flickering pixels on my panel. Using the same setup and software but switching to my previously purchased curb-cut 2.5mm pitch 64x64 panel it works perfectly.
I'm looking to get this new panel replaced (order 3029327-8699415903).

What --led-slowdown-gpio setting are you using? I think this can go up to 5 if necessary. Different panels just have different timing requirements; swapping the panel is unlikely to resolve this.

I had been using 4 for the slowdown and thought that was max, adjusted to 5 and it's buttery smooth. Thanks pburgess!
