Emissive material jitter on moving object

Hello!

When I add any object to movable pawn with emissive color, it starts to jitter on movement. Rotating camera looks like this:

The screenshot is from the default ThirtPerson project. Only thing I did is attached sphere object to the character with a following material:

If I disable motion blur, jitter becomes much less, but still noticeable.

Ok, the problem was in the TAA, changing it to FXAA removed the issue (still, I needed to lower the blur amount).

This didn’t work for me, but unticking Motion Blur in Project Settings > Rendering did.

the motion blur was a life saviour
