Hi does anyone know why it is having this color problem?

It is visible in the headset and monitor with Oculus Rift and Unreal engine demos on an Alienware laptop.
Looks like an optical prism effect, does it happen with other videos/demos with straight dark lines on white backgrounds at the edges of the screen? If so the primary suspect would be the lenses, and might even be a known but usually unnoticeable issue with the dev kit you’re using.
If you can’t replicate the effect with other programs displaying the same type of image, one with sharply defined dark lines with white backgrounds right at the edges, it might be a weird deliberate effects choice, but that seems unlikely.
I think I’ve started to figure it out - it is related to movement… the rollercoaster tracks change in color is related to its change in position over time…
Besides being in startup splash screens it is also in another Unreal engine demo:

It involves the user constantly flying forward and it has a fairly large yellow border around the view…
It seems to involve the different color channels being combined where they are from different moments in time.
It is on the monitor and headset. I thought in a prism it fades between colors in the spectrum - this one seems to involve distinct color channels.
Look at the plant/tree in this image:

Like I said it is on the laptop monitor too - which is what the photos were taken of.
I found it very noticeable.
It is in both of the Unreal engine demos.
What you might be seeing is correction for the chromatic aberration caused by the Oculus optics. Basically, the lenses in the headmount affect the red/green/blue channels slightly differently. To correct for this in the headmount, you’d need to introduce an inverse aberration in the rendered image. See this thread on the Oculus forums:
Thanks for that - they didn’t adjust the headset for me and the problem was very noticeable both with the headset on and on the monitor.
