Show Preview Offset bug

Hi guys,

Is it me or is there a bug in the Show Preview Offset view option?

I made a screencast because it’s much easier to show than to explain:

Everytime I tried out the Offset Curve filter, I was confronted with this kind of bugs in the Show Preview Offset, so my guess is there must be something wrong somewhere.

Any ideas?

Fixed it.

Great! Thank you. Looking forward for the next update.
