Object shakes only after rendered with Octane

[inesalpha]

Hey !
I've having troubles with an octane render.
There is one object in my scene that seems to shake very slightly during the whole scene.
It's a pretty simple object, a rectangle spline wrap that looks like a ribbon.
I render with Pathtracing and the texture is transparent.
When I made a preview before the final render, with directlightning and a diffuse mat texture, it didn't shake.

Attached is the part of the video where the problem happens.
It's the ribbon that comes in the foreground, you'll see it.

Thanks in advance for your help.

Plus check rayepsilon value

Hello @aoktar !
The ray epsilon value is set by default so 0.0001
I've never touch it, which value should I try ?
I actually changed the render to directlightning diffuse to make the render faster.
Attached are my octane settings.

Thanks again for your help.
