I got an error trying to exit xlights. I have an issue and it might not be related. But here's what I got. HolidayCoro AlphaPixa 16. 10 string Mega Tree and 3 arches connected to the controller. I have a universe assigned to each string. The Mega Tree's last 2 strings lag all the time. The only one of the 3 arches works. If I use Xlight 2012B to test each string they all work. I can turn them on all white, they can do the RGB testing. I don't have any string that cross over universes.
