UE5 CineActorCamera view flickers in small previz screen


It doesn’t do this in full screen mode for the camera, and it actually worked fine for hours then after animating the camera and rendering out a test shot it started flickering. Nothing was added or taken away, or changed. The movement was a basic slide on the X axis. In my world something works or it doesn’t, it doesn’t change it’s mind later. That is the part that makes no sense to me. Please help.
