Screen Flicker / Tearing after beta update

[mgworek]

Anyone else having display problems after latest beta update?

Rebooted 3 times, it only happens on the iMac display. My external display is fine.

Video attached.

Thanks

I've been having the same problem for a while now, it happens intermittently. I was on sierra, but downgraded to el capitan again, but the problem is still there. I thought it was my monitor as I bought it at the same time the problems happened. Good to know that it might just be a software problem. I have win10 on a bootcamp partition, and i haven't seen any flicker there.
