Woocommerce odd behaviour

Hi,

I have a little problem with woocommerce.

When editing a product, the page is fine, until… You scroll past half way on the page. After this point in the page starts to move up and down very slightly in a sort of rocking motion. it looks like the left and right sidebar are moving up and down by 1px or something

You can see it in the attached video

I have disabled all plugins apart from VC and Woocommerce but the problem persists.

I have also noted that there is a dotted outline on the main product image where it looks like the container is out of alignment or something? See enclosed pic.

Other than that your theme is mind blowing 🙂

Many thanks

Dean
