No they are not. I’ve checked on safari and on chrome.
On the homepage connected to that link I sent – On the first page they are all the same (cropped)
On the second page, the top four are cropped and the bottom right is a square.
On the third page, they are all squares.
Also – on all pages using the homepage template, I have the masonry setting for blog posts and instead of showing the designated 6 posts per page, they all show 5 – leaving the lower right section empty.
