I searched on this topic but didn't find anything conclusive...
My proxy clips of 3K 29.97 (build 17 i believe) are flashing when I play them back in my source viewer window and on the outboard Kona display. When I frame forward quickly I can see it's actually a geometry shift happening every frame where it jumps from windowed to full squeeze each frame.
With clients in the room, it's really hard to explain this away and see the shots for what they are. I have worked with lots of Red footage and never seen this till now. Nothing about the system has changed. Any help is appreciated.
