Led lamp flickers visibly at low brightness

[BigMike71]

Led lamp flickers visibly at low brightness, sometimes more sometimes less.
I have several Teckin SB53 (and also other brands) where it stands out with a setting of color # 0000000001 or # 0000000002!
When testing different versions, there is no flickering up to version 8.1.0.4, after which this occurs, even with the latest 8.2.0 release.
in the Arduino Core I found them here:
esp8266/Arduino#7054
esp8266/Arduino#7057
