Random colors - APA102

Hello everyone.
I've just finished all the instalation of my led.
Led APA102, Raspiberry PI 3b+ (with OSMC), power supply and so on.

I did exactly as the tutorial of hypercon even for the settings of hyperion (ofcourse just changing the device to APA102 and the mount of LEDs).

The issue that I have at the moment is that the lights are randomly changing colors independent of what ever is playing on the TV (even if image is static).

I'm uploading the log.

Does anyone have a clue of what to do?

Hi guys, I've found the issue..
The GND pin from the raspberry was not connected to the same GND pin of the led causing flickering led.
