I have 3 snowflakes (2 98 pixel (12v) and 1 496 pixels (5v)). They are both running off one esp32 running WLED.
When I run a show through xlights, everything works fine but when running the WLED sequences, the larger snowflake flashes white intermittently. It seems to occur randomly but fairly frequently.
After having run my show through xlights, things seemed better until I powered off and restarted the esp32.
I double checked all connection and everything seems to be good there.
