This happens during a page scroll.

Important note
It doesn’t always freeze to a point where you could take a screenshot but it is definitely there and it’s between sections (i.e. between ‘Introduction’ and ‘About me’, between ‘About me’ and ‘Highlight Projects’ and so on…)
I’ve been trying that and then activate them one by one – it didn’t work..
