Question What could create runtime blur/displacement of a prefab?

What could be causing the insane jitter shown in my screenshot?

I have a few objects that look fine in the editor and look crazy blurry during play as if they were vibrating. Attached are images of both.

Other prefabs from the same package, in the same scene don't have the same issue. I'm quite new to Unity and I've tried changing options on the shader but can't find anything that helps

Please save me

 

This looks like motion blur, a postprocessing effect.

If it were simply fluctuating the transform.position you couldn't even capture it in a screenshot, so it has to be a postprocessing effect (or a custom shader effect that looks like blur).

 

Switching off motion blur indeed fixed it. I didn't think it could be responsible before when it was only some objects!
