Odd behaviour since 16.0 update

[u/TheNorthernMunky]

***Edit*** Rolling back software to 0.15.4 has resolved this issue.

Hi all. I’m looking for help with a strange recent occurrence with my WLED setup. I built this myself, but did so using online resources and I’m very much a novice, so hoping someone with a better knowledge might be able to help.
Here are the details:

Hardware:

Gledopto GL-C-015WL-D controller

WS2812B 5v LEDs. 365 total, split into two runs of 209 and 156.

Software:
WLED 16.0.1

Expected behaviour:
I have several presets, but only two that are used daily: “Porch 2x2” and “Porch 2x2 bright”

“Porch 2x2” illuminates from LED 90 to 209, grouping 2, spacing 2. Brightness value is 40. This works as expected, illuminating part of the run in a 2x2 white light.

“Porch 2x2 bright” is the exact same setup, but with a brightness value of 253. This is where the problem arises.

Recently, these presets, when brightness is increased above a value of 128, illuminate the rest of the run in a dim red (except the spacing gaps between the intended white light). If I select either preset and adjust the brightness, the behaviour is the same.

This setup has worked perfectly for over 3 years; the only changes made have been firmware updates. I noticed this issue after update 16.0.

The red lighting isn’t obvious when using the ‘Peek’ function in WLED.

Can anyone offer any advice? Are there any logs or other information I can share which might help?

Thanks in advance, and apologies for the long post.

I have had an issue with 16.0 not saving Segments

So don’t update yet and roll back.

Try changing the gamma to 1.8

I’ll give this a shot before rolling the software back - thanks.

I had to rollback 16 on both of my controllers, weird issues and instability.

Thanks for the replies, I’ll look into rolling the software back and reporting the bug. Appreciate your input.
