I cannot get scrolling text to function correctly with my 32x8 ws2812b led matrix. The same settings work without issue on other esp32 wled controllers.
My settings are 256 ws281xb leds, 32 width x 8 height, serpentine, horizontal, bottom right. I even updated to the latest ESP32 firmware and the same behavior persists.
Our test is completely normal, please confirm that your settings are correct. If you still have problems, please contact customer service
