previous image is not completely erased(Disable postprocess)

I mean White semi-transparent edges when moving.

(I suppose it is reversed in color and moved image of previous frame with big transparency.)

How to disable such post effect?

tip: It is very visible in Oculus VR if you start standalone application and then press Start button. (fps became lower in 10 times so you will see it precisely. And I didn't see such effect on usual monitor.)



p.s. It is very visible between light and dark parts of image.

    Due to switching times in the display, you may observe some interference between consecutive frames. Without any correction, it looks like a gray trail behind black objects. We apply a correction that reduces this "black smearing", but it is not always 100% effective and there can be very slight (much slighter than the smearing) "ghosting" of the negative image. If you see this, the best solution is to reduce the contrast of your scene. Try to avoid sharp transitions between light and dark.

    Maybe better do such effect tunable? And allow user decide whether he/she need correction or not.
    I believe that there is a checkbox for it, it should exists.

    How do you want to tune it? I'm pretty sure you would never prefer the heavy black smearing to the very slight ghosting you get today.
