Smearing / Motion Doubling - not Judder!
Hi all. Working in Unity, I'm getting a doubling effect on any fast moving object that's moving laterally (side to side). It's not judder as everything else is solid... just objects that quickly move ...
No worries mabsey! We're all in it together :)
Cybereality, I did some more tests with very low contrast colors (grey object on grey background) and was still having the same issue. After some research I found this post by Michael Antonov about Asynchronous Timewarp and found this screenshot from Couch Knights that looks exactly like the doubling i'm seeing:

In his post, Michael states:
"Animated or moving objects cause another artifact with ATW: because a new image is generated just by warping the original image without knowledge of the movement of objects, for all ATW-generated frames they are effectively frozen in time. This artifact manifests as multiple images of these moving objects — i.e. judder."

Will this always happen with fast moving objects near the viewer? Do you know if this is improved or fixed in CV1?

I'd imagine it's just black smear. It happens where you have objects of contrasting colors.
Sadly it's a limitation of the panels used and can't really be fixed.
