Curves Ghost (Snapshot) not accurate

Hi all!

I think that the curve snapshot feature in the Curve Editor is very awesome specially 'cause there’s no such an option in Maya or 3ds. It always worked fine, but today I have this pretty inaccurate result :confused:

As you can see (clearer in the circled areas) the ghosted curve doesn’t follow the curve but still passes through every keyframe.

Is this a known issue? Has anybody a solution for this. I’ve tried restarting Blender and moving the keyframes a little before taking the snapshot but it stills the same. The error happens either with normalized curves or non-normalized.

Thanks in advance, dudes :wink:
