I had a hero header section with a background image - this image was absolute, the section was sticky. The rest of the page content then scrolls up over the top of it. This works perfectly on all sizes, however on mobile and tablet (both android) if I scroll up really quickly the background image flashes in-between page sections. It’s only occurs between page sections as they ‘re-load’ on scroll up.
I’ve removed it entirely for now so I can move forward.
I feel like it’s because these page sections momentarily go transparent when they’re not on screen. I’ve played with z-index, relative, lazy load, and a few other things but I really have no idea what’s causing this.
Anyone familiar with this? Is this a bug?
