tearing, stuttering, only on black backgrounds, vrchat just flashing black spikes everytime.

[Yen_25514]

Hello! This is a weird one, but I'm having an issue with my new Quest 2 headset. I have it plugged into a USB 3 port, I have a 4090, and I have enough RAM not to worry about it. 
I launch vrchat, and every time I see a black texture, boom, the headset starts spiking these black lines, flashing them fast and giving me a headache, making it unplayable. This doesn't happen on vrchat when I look at it on my desktop whilst in vr, and it doesn't happen when I open Steam VR to look at my desktop, but it will continue behind my desktop in vrchat. 

I still also don't even know what settings to put it on, currently in the oculus software I have it set to the default everything, 
I usually get his message every 20 seconds:

 And the rest from the debug console is just this:

on top of that, I have set the Oculus app to use my desktop headphones and earphones, not my Quest 2, and the same on VRChat and Steam VR. Now, why does it just say in the control panel in sound management that my Quest 2 headphones and microphone are being used and show 50% audio coming through? They lit up green with nothing using them. So I disabled them, but still the issue continues. 
I need a fix, please.
