Have issues with segment spacing

when i try to add spacing to a solid color (white), if i apply one to spacing, the string of 20 will bring in another color instead of not going dark. Or when i have a srtring of solid white in preset and I select an other preset of white with 1 spacing, the string blinks every second pixel and come back all white again

what version? try updating to 0.15 beta 2 or even nightly build (0.16 alpha)

It’s version 15.0
On a quinled quad or ESP32 vroom no difference
