Generic root motion jitter?
Hi, I have a generic animation that's been acting weird lately, for some reason it jitters a lot the faster it moves. I'm astonished because the same thing happens on a new project, in this case a simple cube attached to a single bone that moves up and down.

The only new thing I've been doing was manually modifying the f-curves in blender, which I thought was the issue but I can't seem to replicate it. Anybody encountered something like this before?
Here's the object in Blender:
