Having trouble with my ECG-P2 and xLights. Running 4 strings in a row, injecting power at both ends and in the middle. 5V 2811. The pixels work as expected when running the ECG-P2 test pattern. When running with xLights, channels 1-1024 works fine (univ 1 & 2), 1025-1364 are off, and 1365-1536 light up but the colors are offset. Channels 1537 and above have a few random pixels lit but do not respond to xLights commands. In the ECG-P2 String Stats page I see I am getting Univ Overruns, but I haven't been able to get the configuration set between the P2 and xLights where I don't get the overruns. I'm stumped since they work fine with the test pattern but not with xLights. Any thoughts as to what could be wrong?
