Black flashes on playback on GUI

PostMon Jun 03, 2019 12:24 am

On all 3 of my Mac pro 5,1s I am getting black flashes on source and record viewers.
It is random and mostly within a few seconds of hitting play but does occur later as well.
Cut, edit and color pages...All the same.
The footage is 25fps HD XAVC so very easy to decode and not happening on V15.

Two machines have 16b2 and the third 16b3.

Hardware specs as below except machine 3 which is a Mac Pro 4,1 with 32 gb ram.

Not happening on the output of the decklink cards. Only on the GUI screens

Cuda Driver version

Anyone else seeing this
DR Studio, 2012 Mac Pro 5.1, 10.13.6, 2x3.46GHz 6 core Intel, 96 GB ram, GTX 1080Ti 11GB graphics card.
USB3 card, BM SDI 4K card, SSD boot disk, 3x4TB SSDs in raid 0, 12TB HDD backup.
Tangent Elements panel, FSI DM240

I have done jobs on 3rd party systems and seen quite a few GUI issues on MacPro based systems. I even had Deliver Page failures that worked perfectly when rendered with a 2014 iMac!
Resolve 16.2.6
Mac OSX 10.14.6, Hackintosh i7 8700 32GB RAM, Radeon RX 580 8GB
Decklink Studio 2, FSI LM1770 Monitor
