Random Flickering on Alpha9

Hello hope everyone is doing well, I am wondering if this is a known issue and if there is a fix for it. Hardware: rpi4 , ws2812b Connection: GPIO18 Build: alpha9 from GitHub releases. On boot, the boot effect runs beautifully/perfect, but after that the leds flicker uncontrollably. This is when I fresh installed alpha9 manually. But when using Wled as a test or even the Hyperbain image, the leds respond perfectly. Is there an issue with alpha9 not sending the right data signal? I have triple checked my wiring this is not a grounding or common grounding issue.

So i just tried a fresh install of buster then installed alpha9 and same issue. Is there additional steps needed? (yes root service is enabled)

Here are some logs since boot.

This has resolved it for me

In my /etc/modprobe.d/raspi-blacklist.conf I added the following:

blacklist snd_bcm2835
blacklist i2c-bcm2708
