Why does this picture frame appear thicker, despite having the same stroke size?

How do I get the picture frame on the top right to appear as thick as the four surrounding picture frames?

Thank you!

I tried what @v_kyr suggested in your original test file and it looks fine to me. Have you changed the alignment of the image and text frames by a small amount as well?

The problem could be that you have got stroke on the image frame AND on the text frame below it.

If the lower part of the image and the upper part of the text frame are not overlapping perfectly, then where the two strokes meet you could be creating what looks like a double thickness on your lines - because there is two lines next to each other.
