Think I have more ? with the more things I try. Hooked up my Gen 10 instead of using the house ref. It seemed to start off better and then get worse. The video trouble is it seems to be going back a frame every now and again – like playing 1,2,3,2,4,5,6,5 but it is stay in sync so those frame as just to help explain it.
It does seem like restarting the Mac is fixing it for a bit. But I cannot figure out what is triggering it, once it starts it starts happens every few seconds.
This is a bit frustrating since it is taking forever to get a clean master and confidence is not very high.
