I see the red green and blue colors separatly when I move my head

Hi,
I just received my Hololens. After the update I see the 3 colors RGB separated around the the cursor (and other holograms) when I move my head. there is a little delay between the 3 colors.
when I move my head left to right the 3 circles of the cursor are clearly visible.
I recalibrate but this has not change anything.
What can I do?

I've been told this is normal - recommendation is to avoid using strong whites with head tracking movements (like the cursor). In my app, I use a blue cursor and do not have any issues like this. My guess is that they'll update the default cursor to prevent this in future release.
@Jerome,
here is the section of the documentation that talks about the issue.

that's it! exactly the problem I suffer. I hope they can optimize this by code in a future update, because its the main problem of the Hololens for now. I can see artifacts around everything in white when I move my head.
I'd say it's more of a hardware limitation than software... Maybe they can do some software wizardry to fix it, but unlikely. Basically they're doing something similar to how a DLP (DMD with color wheel) works, they will flash red/green/blue independently and our eyes fuse these colors together to produce the color and brightness intended. In other words, each color is flashed in varying sections of the screen for varying periods of time and our eyes will produce color and brightness mixtures, similar to how videos work, when they're really just a series of still images.
I believe they're already doing this at a pretty high refresh rate, but if the image in question contains a high luminosity mixture of all two or more colors, color separation can occur in fast movement where the location of one color is now separate from the location of the second color (with respect to the eye's focus), and so the fusing doesn't occur.
With more powerful hardware this may be overcome, or so I assume. I have not studied wave guide displays all that much myself, so I don't know if there are any inherent limitations to the refresh rate.
