Fullwidth section rendering

Hi There,

Firstly, I love this theme, thank you for the great features and support! On my site I have various full width sections which have a coloured background, such as on this page:

When I load the page, the full width section first loads as standard page width, before rendering to full width – this doesn’t look great as looks like it’s flashing in and out and re-loading. Is there a way to stop the pages doing this for full width sections?

Thanks!
