Image Subtly Shaking in Canvas Window while Rendering

Hi Ken, and company,

Has anyone ever experienced the image in the canvas window slightly moving while rendering in HD? I've never seen anything like it. It plays back fine and stable once rendered. The files were in ProRes 422, with some color correction. Any thoughts on how or why this might be happening?

Thanks,

Kenn

Kenn,

I have no idea. Is your Canvas window set to Fit to Window amd RGB?
