I created a test UE4 C++ project using CameraDirector to move the viewer position. The CameraDirector is a C++ class and the viewer position is controlled by SetActorLocation and SetActorRotation functions. When the viewer is far away from origin ((0,0,0) coordinate) , the rendered image has glitches as the position and heading change. It does not look like bad frame rate, it is more like the resolution of the position is messed up. The problem only happens if I use nDisplay. Has anyone seen this before? Thanks
