Pimax eye tracking suddenly doesn't work right

[Gunfreak]

Last week my Cystral worked perfectly fine, today I tried a mission and there is something "off" with the eye tracking, as I move my eyes I can see the foveated rendering move, and it's shimmering, it's very in your face and I can't ignore it. 

I've tried to recalibrate eye tracking, I've restarted the PC and crystal several times, I've tried 72mhz and 90mhs modes. 

I've followed the pimax eye tracking trouble shoot page, and everything checks out there. yet there is obviously something off. I've tried several aircraft and maps, it's more noticeable on kola with snow and the light conditions, but it's still there on Caucasus in summer too.

 

Here's a video, and there is clearly something off.
