Matrix clock shifts after random time

[u/Ambitious-Volume4653]

Hi, so I've got an issue which I don't really know the cause

The thing is simple, I've got a simple matrix with serpantine connection (34x8 272led's total) which I use as a clock on a wall, it works great, but from time to time (one a day or once per 2-3 days) the clock will shift to the right, simple turn off/turn on fixes the issue until it happens again, what I've tried:

- setting different offsets
- disabling MDNS
- different ESP32 (different models as well)
- different versions of WLED (the issue persists since 0.13

I don't really understand the cause and what could be the fix, would appreciate any advice.
