I just started getting the issue.
So pissed off... UGH.
I was working with Adobe Premiere and it went into red checkerboard mode and totally froze.
Restarted my machine and now I can see flickering and a faint checkerboard pattern on my desktop, which goes away if I move the mouse or start typing. It comes back after about a second of inactivity.
WTF... so bummed out.
Did you update your OS? Helped with mine.
[doublepost=1482165486][/doublepost]AT THE MOMENT ALL ISSUES ARE GONE AFTER 10.12.2 UPDATE!!!
I just batched rendered 60 clips from Red format into Prores Proxies in Adobe Media encoder and nothing happened.
The actual render was FASTER than in FCPX.
And as I said before the login glitch is gone as well.
Machine seems to be working fine.
I'm not convinced yet though because it took so long to get here.
Also I'm pissed because I spent $550 on software that I'm not going to use now because I'm going back to editing in Adobe CC.
Until the next catastrophe - I'm traumatized, haha.
