What happened?

after setting the effect to plasma and the color palette to random cycle, it works fine until the next day, where the palette becomes mostly red but flickers to blue occasionally. this happens on esp32 with WLED_0.15.0-b1_ESP32 firmware and can only be resolved by a reboot

To Reproduce Bug

use esp32 and WLED_0.15.0-b1_ESP32
use random cycle palette
I have only tested with the plasma effect, but given the changes to palette blending it will most likely happen on other effects

Expected Behavior

the random cycle palette should be consistent after the first few hours

Install Method

Binary from WLED.me

What version of WLED?

WLED_0.15.0-b1_ESP32.bin

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

No response

Anything else?

this happens on 3 different setups. all use esp32 with WLED_0.15.0-b1_ESP32 firmware, will test esp8266 with equivalent firmware soon
