Hi,
First of all, the title isn't clear enough so I'm sorry about that.
I have a RPi 3B+ running Raspian with around 220 WS2812B leds connected via SPI + STK1160 grabber and a 12A 5V power supply. No logic level, but a 470 Ohm between the RPi and the data wire, soldered. The cable between the RPi and the strips has around 1m.
The 4m strip is split in 4 smaller strips and the ground + data is soldered between then. The +5V is directly connected to the power supply.
The issue that I'm having is completely the oposite of the majority. I can light up all my leds in white with no issues and no weird/orange colors, but I get random and colorful colors when I get dark scenes OR I set a dark color (close to black up to full black) manually using the webconfig or hyperion-remote.
If I enable the grabber on a bright movie and/or manually select an effect or a bright static color the leds lights up beautifully.
I also tried the offical test (python and C) scripts from the WS2812B library, no issues at all.
My first thought was related to the blackborder detection, which I tried to disable/enable and change settings. I also thought it could be related to the backlight color or backlight threshold. No lucky.
My hyperion is compiled from the master branch and it is up-to-date:
