Lightbox thumbnails flickering issue when page loads

Good day,

I’ve noticed that lightbox thumbnails flicker once when page loads. I find it a bit annoying and of course such page will not be approved by a potential client.

Example: a site has menu tabs: ‘about’ - ‘projects’ - ’ fotos’, when you go from ‘projects’ or from ‘about’ to ‘fotos’, ‘fotos’ page contains image thumbnails that flicker once the page gets loaded by the browser. It looks like it flickers only once…at the moment when the page loads.

Is it related to lightbox JS or this is thumbnails producing such an ‘effect’?



It’s impossible to say without seeing an example.
