Hey everyone. Been using WLED for a while now, but new to the community. I just updated my board running out Christmas lights to 0.15.0 a couple of days ago and ever since then the lights periodically fade off for a split second and then back on. Seems to happen around every 2ish minutes, although I’ve not actually watched them long enough to know if it’s consistent or not. I’ve uploaded a video [here](https://www.icloud.com/photos/#/icloudlinks/0e4lHS_kRNmO6s59p5-2bfJwg/0/) where you can see the lights fade out and then back in using the peek feature. Any ideas if this is a new bug in 0.15.0 or if I’ve configured something wrong? Thanks! ---

Pretty sure this is related to a fix/change in 15 that updated how timers/repeat counts/etc tracking in effects was handled. I see it too in that about once a minute, the effect running seems to “fade out” and then restart (one of the fairy light effects). Under 14.x it worked continuously. From what I’m reading, a change in the effects code broke a few effects and it seems that is being fixed for 15.1. You can read about a similar report (and think same problem) here: > [@Tweaking effects settings?](https://wled.discourse.group/t/tweaking-effects-settings/13613/17): > > Was able to get .bin files (once I logged into github -Doh!). Resolves the issue as far as I have been able to watch, I quit after about 10 mins. As noted, the previous version was pretty consistent on my devices. Thanks to @dedehai for all the fast work! christmas_tree sunglasses So for now, prolly either 1) live with it til 15.1 is released, 2) revert to 14.x or look for an try one of the 15.1 beta/nightly builds ---

Just downloaded the 16.0 Alpha release and confirmed that in the effects I was seeing the periodic “fade out and back on” problem it appears fixed. ---
