I am working on website https://www.designersheds.com.au and it has strange flashing after a page loaded. It shows correctly and then blinks. This behavior occurs in Chrome and Mozilla, but not in Opera and Edge (although in Edge some styles don’t seem right). All scripts are in the footer. And all styles are in (I use Autoptimize Plugin for WordPress).
The website is on WordPress with Genesis Child theme.
If anyone can point me in right direction, I would be very grateful.
