Random effekt on led matrix

[Wollsen]

I tried to make a random effect in a led matrix, it works fine, but occasionally when I go in and change the settings, speed, size and numbers, the background colour sometime changes. and then I have to delete the effect and start over again.

any ideas

I've not seen this bug before. Are you just running one rect with one timeline?

I have been trouble shooting the problem at seem to appear only when I use ledbars in multibeam setup
