Hey @arminunruh thanks for your help so far,
All was working nearly perfectly with my overlays but after the recent update, my "Contact" page is now showing a "flash" of the content when it loads, rather than smoothly appearing.

(Click the read more or Contact button)
It's weird because my other overlays don't do this, even though as far as I can see there's no difference in the way they are set up or any strange code differences.
I did have some opacity effects on the contact page which were causing a similar thing to happen, I've removed them and it was all good but now the problem has returned.
Any insight you might have would be super, thank you!
