Site flickers on dropdown open

Hello hive mind!

You may just be my last AND BEST hope.
It may just be that my site is too layered, but when I open any other the FAQ dropdowns in the page it causes the whole thing to flicker. Quite a big dampener on the user experience.

I’ve tried recommendations on this forum and others, but sadly to no avail. Can you help?
