Strange appearance of lines ending abruptly at cubemap boundary.

[tsloan1377]

I have noticed a strange effect that I haven't been able to track down and solve. In my animations, while I am drawing many lines, there are cases when the vertical spanning lines appear to break along the boundary of the cubemap edge in the center of the screen. I have attached an image as example, where the lines are broken, creating an apparent square in the center of the frame.
Wondering if anyone knows what's causing this?

Hello, maybe you have to change the 3D settings of your graphic card. Do you have Nvidia?

Sorry for the delay,
Yes I'm using an Nvidia GTX 1080Ti
I'll double check my 3d settings.
