Video Copilot Optical Flares light flickering problem

Been learning a lot of Adobe After effects.  When I would render a video, the light flares would flicker.  It may seem normal at first, but when you see that it's a distraction, you realize it's not how it is supposed to work.  On my computer, I have a built-in Intel 4000 HD graphics.  And I had set After Effects to render using the GPU.  I changed it back to the CPU and the flickering is gone.
