Can not turn on LEDS with version above 14.0

[tomlut]

What happened?

I have a Hyperion ambilight set up behind my TV consisting of:

250 LED WS2812 on segment 0, UDP sync interface enabled for main segment
20A 5V power supply (multiple injection points).
Quinled ESP32, data pin GPIO26

Using version 14.0 this works perfectly. Syncs with video frames and LEDs on/off control operates as expected.

Using any later version (14.1, 14.2) installed and configured fresh, (to eliminate update json config migration as the cause) the LEDs initially turn on but after turning off the LEDs either via the WLED web interface or the Hyperion interface the LEDs can not be turned back on.

To Reproduce Bug

Install 14.1 or later version.
Turn off LEDs, attempt to turn LEDs back on.

Expected Behavior

LED control and sync to operate.

Install Method

Binary from WLED.me

What version of WLED?

14.1, 14.2

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

No response

Anything else?

Config file:

wled_cfg_tv-led-strip.json

I was able to replicate this using Hyperion on v0.14.2, but not with a build of v0.15. I am still investigating. Hyperion sets a transition time of 0 - I think this might be related.

[blazoncek]

yes, transition time 0 causes issues on 0.14

OK - I think you can close this as a duplicate of #3720 then.
